Our Top 7 Best Push Button Start Kit Retrofit Reviews – Expert Tested & Recommended
1. Easyguard Smart Keyless Entry Retrofit Kit with Push Button Start and Remote PKE Car Alarm System
🌟 Key Features That Stand Out
- ✓ Passive Keyless Entry (PKE): Automatically locks or unlocks the car as you move 1-3 meters away or closer.
- ✓ Remote Engine Start: Allows you to start your car from a distance to pre-cool or pre-warm the cabin.
- ✓ Universal Compatibility: Works with most DC12V petrol cars, including manual and automatic transmissions.
- ✓ Comprehensive Alarm: Features a vibration alarm and remote trunk release for added security and convenience.
💡 Why We Recommend It
This Easyguard system is the definitive choice for those who want a complete modern overhaul of their vehicle’s entry and ignition. It doesn’t just stop at a push button; the Passive Keyless Entry (PKE) is a game-changer. Imagine walking up to your car with your hands full of groceries and having the doors click open automatically. It adds a level of luxury and convenience that usually only comes with brand-new vehicles.
What sets this kit apart is its reliability and the depth of its features. The remote start is powerful and consistent, which is a lifesaver during freezing winters or scorching summers. While it does require a professional to install, the final result is a seamless system that feels like it came straight from the factory. It’s durable, responsive, and significantly boosts the security of your car with its integrated alarm features.
🎯 Best For
This product is ideal for: car owners looking for a full luxury upgrade including hands-free entry and remote climate control.
⚖️ Pros and Cons
✅ Pros
- Flawless hands-free PKE entry
- Robust remote start performance
- High-quality, durable remote fobs
- Integrates well with existing systems
❌ Cons
- Needs professional installation
- May require extra bypass module
💬 What Customers Say

2. Easyguard Smart RFID Push Button Engine Start Kit and Keyless Go Retrofit for Universal 12V Vehicles
🌟 Key Features That Stand Out
- ✓ RFID Security: Use a transponder to arm or disarm your car, preventing unauthorized engine starts.
- ✓ One-Button Operation: Converts your traditional key-start ignition into a modern push-to-start system.
- ✓ Compact Design: Minimal footprint, making it easy to mount the button on your dashboard.
- ✓ Safe Ignition: Only allows the car to start when the RFID sensor detects your specific key tag.
💡 Why We Recommend It
If you want the push-button aesthetic without the complexity of a full alarm system, this Easyguard RFID kit is the perfect middle ground. It focuses on the core experience: ditching your physical key for a sleek button. The RFID transponder acts as a silent guardian, ensuring that even if someone breaks into your car, they can’t start the engine without your specific sensor tag nearby.
This kit is incredibly popular because it does one job and does it very well. It’s simpler to install than the PKE versions, though professional help is still recommended to ensure your steering lock is properly managed. It’s an elegant solution for older trucks or classic cars where you want to add a dash of modern technology without cluttering the vehicle with extra sensors and wires.
🎯 Best For
This product is ideal for: budget-conscious DIYers who want a sleek push-start look and basic anti-theft protection.
⚖️ Pros and Cons
✅ Pros
- Very affordable price point
- Simple and effective RFID security
- Sleek, factory-look button
- Highly reliable ignition control
❌ Cons
- No remote start feature
- No automatic door locking
💬 What Customers Say
“Installed this on my ’98 Jeep. It works perfectly and gives the interior a much more modern feel. The RFID tags are small and easy to carry.”
— Verified Buyer
“Great value for the money. The button feels solid and the system hasn’t failed me once in six months of daily use.”
— Verified Buyer
3. Banvie 3-in-1 Car Keyless Entry System with Remote Engine Starter and Push Button Ignition Retrofit Kit
🌟 Key Features That Stand Out
- ✓ Remote Start/Stop: Warm up your vehicle from your home or office using the included remote.
- ✓ Auto-Lock Security: The system automatically locks the push button 30 seconds after the engine stops to prevent theft.
- ✓ One-Way Alarm: Includes a siren that triggers if the car is shocked or a door is forced open.
- ✓ Trunk Release: Remote control support for popping the trunk with a simple button press.
💡 Why We Recommend It
Banvie has hit the sweet spot between functionality and affordability with this 3-in-1 kit. It provides the essential features most drivers crave—remote start and a push-button ignition—without the high price tag of name-brand systems. It’s an incredible value for anyone who wants a full-featured system that includes an alarm siren and trunk release control.
The safety features are particularly impressive here. The 30-second auto-lock for the ignition button is a smart touch, ensuring that even if you forget to lock your doors, a stranger cannot simply hop in and drive away. The alarm system is sensitive and loud enough to be a real deterrent. For the price, you get a robust set of features that are usually reserved for much more expensive retrofit kits.
🎯 Best For
This product is ideal for: users who want remote start and alarm functions on a tight budget.
⚖️ Pros and Cons
✅ Pros
- Excellent value for the feature set
- Includes a physical alarm siren
- Remote trunk release is very handy
- Safety auto-lock feature for the button
❌ Cons
- Remote range is average
- Instructions can be slightly technical
💬 What Customers Say
“The remote start works like a charm from inside my house. It’s so nice to get into a warm car in the morning.”
— Verified Buyer
“Simple to use once installed. The alarm gives me peace of mind when I have to park on the street.”
— Verified Buyer
4. 3T6B Passive Keyless Entry Retrofit Kit with Universal Engine Push Start Button and Smart Key System
🌟 Key Features That Stand Out
- ✓ Touch Password Entry: Features a backup touch pad to enter a password if you lose your remote.
- ✓ Smart PKE Technology: Hands-free locking and unlocking within a 1.5 to 5-meter range.
- ✓ Pre-Cool/Pre-Warm: Remote start function specifically designed to optimize cabin temperature.
- ✓ Search Mode: Easily find your car in a crowded parking lot with the remote car search function.
💡 Why We Recommend It
The 3T6B kit stands out because it solves the “what if I lose my keys?” anxiety. The inclusion of a touch password entry pad is a brilliant safety net. This means even if you’re out hiking and drop your remote, you aren’t stranded—you can simply punch in your code to get into your car and start it up. It’s a level of redundancy that few other kits offer.
Beyond the password feature, the PKE response is snappy and the build quality of the fobs is impressive. It’s particularly popular with Toyota owners due to its wiring compatibility, but it works well across most 12V platforms. The system feels very “intelligent,” detecting handbrake status before allowing a remote start, which prevents accidental movement.
🎯 Best For
This product is ideal for: drivers who travel to remote areas and want a backup password entry system.
⚖️ Pros and Cons
✅ Pros
- Emergency password keypad is a life-saver
- Excellent PKE range and sensitivity
- Oil pump detection for safer starts
- Remote car search is very effective
❌ Cons
- Keypad mounting takes extra time
- Wiring can be a bit complex for novices
💬 What Customers Say
“I love the password keypad! I lock my keys in the car when I go for a run and just use the code to get back in. Best feature ever.”
— Verified Buyer
“The remote start has worked every time, even from the second floor of my office. Highly recommended.”
— Verified Buyer
5. Universal 12V Car Alarm System with Remote Start and Push Button Ignition Retrofit Kit for Cars
🌟 Key Features That Stand Out
- ✓ Shock Sensor Alarming: Triggers a loud alarm if someone bumps into or attempts to break into your car.
- ✓ Illegal Door Detection: Detects forced entry and prevents the engine from being started illegally.
- ✓ Remote Start/Stop: Simple remote engine management to control cabin temperature before you enter.
- ✓ Full Universal Fit: Designed to be compatible with almost any 12V vehicle on the road.
💡 Why We Recommend It
This universal system is a powerhouse for those prioritizing security. While other kits focus heavily on the “cool factor” of the push button, this kit integrates a high-quality shock sensor. This is a vital feature if you live in a busy city area where “hit and run” parking incidents or attempted break-ins are common. It turns your push-start retrofit into a full-scale security upgrade.
The ease of use is another highlight. The remote buttons are intuitive, and the push start is responsive. It provides a reliable remote start function that doesn’t feel laggy. For anyone who wants their car to be harder to steal while also enjoying modern convenience, this kit is an excellent, well-rounded choice that focuses on the basics with high quality.
🎯 Best For
This product is ideal for: city dwellers who need the added protection of a shock sensor and forced-entry alarm.
⚖️ Pros and Cons
✅ Pros
- Excellent shock sensor sensitivity
- Prevents illegal engine starts effectively
- Quick remote start engagement
- Very clear wiring diagrams included
❌ Cons
- Shock sensor may need fine-tuning
- Key fobs are a bit bulky
💬 What Customers Say
“The alarm is loud and the shock sensor works great. It’s actually saved my bumper once already from a neighbor who backed into me!”
— Verified Buyer
“Solid build quality. Everything arrived as described and the remote start works from a decent distance.”
— Verified Buyer
6. PKE Passive Keyless Entry Car Alarm Retrofit Kit with Push Button Start and Remote Engine Ignition
🌟 Key Features That Stand Out
- ✓ Intelligent Approach/Depart: Door locks and unlocks automatically within a 1-3 meter range of the key fob.
- ✓ Auto-Warm/Cool: Remote engine start pre-conditions the car for up to 15 minutes before automatically shutting off if you don’t enter.
- ✓ LED Indicator: Shows the current status of the alarm and PKE system for visual confirmation.
- ✓ Emergency Disarm: Hidden manual overrides available in case of remote battery failure.
💡 Why We Recommend It
This kit is all about a smooth, automated lifestyle. The PKE system is very consistent, meaning you’ll rarely find yourself waiting for the car to “notice” you’re there. It makes the transition from walking to driving feel completely fluid. For someone who uses their car daily for errands, work, and family, this automation saves small bits of time and effort that really add up over the week.
We particularly like the “Auto Warm” feature. It’s set to run for 15 minutes, which is exactly the right amount of time to defrost windows or get the AC blowing cold without wasting too much fuel. The built-in LED indicator is also a great visual deterrent for thieves, as it clearly shows that the vehicle is protected by an active alarm system. It’s a very user-friendly kit that focuses on daily comfort.
🎯 Best For
This product is ideal for: daily commuters who want a seamless, automated “hands-off” car entry experience.
⚖️ Pros and Cons
✅ Pros
- Very responsive PKE sensors
- 15-minute auto-shutoff for remote start
- Highly visible LED status light
- Sturdy remote key fob design
❌ Cons
- Requires extra bypass for chip-keys
- Siren is loud but tone is generic
💬 What Customers Say
“The PKE works like a charm. I just walk up and the doors unlock. It’s so much more convenient than digging for keys in the dark.”
— Verified Buyer
“Easy to use once you get it all wired up. The remote start has great range for my needs.”
— Verified Buyer
7. Smart RFID Push Button Engine Starter Retrofit Kit with Keyless Entry for One Touch Ignition Upgrades
🌟 Key Features That Stand Out
- ✓ One-Touch Start: High-response button for instant engine ignition or shutoff.
- ✓ Auto-Arming: Automatically enters arming mode 15 seconds after the car is parked for effortless security.
- ✓ Engine Lock: RFID detection ring requires the tag to be within 2-5 cm to disarm the ignition.
- ✓ High Compatibility: Does not interfere with existing door lock systems, making it a “clean” ignition upgrade.
💡 Why We Recommend It
This kit is the perfect choice for the professional or experienced hobbyist who already has a keyless entry or alarm system but wants to add that high-end push-button start functionality. Because it doesn’t mess with your door locks or central locking, it’s much “cleaner” to install alongside other upgrades. It focuses purely on making the starting process modern and secure.
The 15-second auto-arming feature is fantastic for those who are always in a rush. Once you turn off the engine and step away, the system secures itself automatically. You don’t have to remember to click a button or swipe a tag to arm the ignition lock. It’s an incredibly inexpensive way to add a major “wow” factor to your vehicle’s interior while improving its defense against hot-wiring.
🎯 Best For
This product is ideal for: owners of older vehicles who want a simple, high-quality ignition upgrade without changing their door locks.
⚖️ Pros and Cons
✅ Pros
- Fastest button response time
- Auto-arming is very convenient
- Won’t mess with your existing door locks
- Highly affordable and compact
❌ Cons
- No remote start capabilities
- RFID ring must be mounted precisely
💬 What Customers Say
“Simple, cheap, and effective. It does exactly what it says. My truck feels ten years newer now.”
— Verified Buyer
“The auto-arming is great. I never worry about someone being able to start my car if I leave it unlocked in the driveway.”
— Verified Buyer
Complete Buying Guide for Best Push Button Start Kit Retrofit
Essential Factors We Consider
When searching for the best push button start kit retrofit, the most important factor is compatibility. Most kits are designed for 12V petrol engines, but if you have a diesel or a car with a complex digital dashboard (CANBUS), you need to double-check the specs. We also look closely at security features like RFID transponders and PKE systems. These ensure that even though you’ve made your car easier to start, you haven’t made it easier to steal. Reliability of the remote fobs and the button’s tactile feel are also key—you want a button that feels solid, not like a cheap plastic toy.
Budget Planning
Pricing for these kits varies significantly. A basic RFID button kit can cost as little as $20 to $30, which is great for a simple aesthetic and security upgrade. However, if you want “the full works”—including remote start, passive keyless entry, and advanced alarm systems—you should expect to spend between $100 and $150. Don’t forget to budget for professional installation. Unless you are very comfortable with automotive wiring, a professional installer (usually charging $100-$200) is a wise investment to ensure your car’s steering lock and immobilizer are handled safely.
Final Thoughts
Retrofitting a push-button start is one of the most satisfying upgrades you can give an older vehicle. It completely changes how you interact with your car every single day. Whether you just want the convenience of remote start on a cold morning or the high-end feel of walking up to your car and having it unlock automatically, there is a kit on this list that fits your needs and your budget. Take the time to find a good installer, and you’ll enjoy a modernized ride that feels brand new.
Frequently Asked Questions
Q: Will this kit work if my car has a chip in the key (immobilizer)?
A: Yes, but you will almost certainly need an “extra bypass module.” This module allows the new system to signal your car’s computer that an authorized key is present. Without it, the engine may crank but will not stay running.
Q: How do I handle my steering wheel lock?
A: Most installers will recommend cutting a spare key and leaving it in the “ACC” or “ON” position inside the ignition cylinder to release the lock, then hiding it behind the dash. Alternatively, some kits come with instructions on how to physically remove the locking pin.
Q: Can I install a push button start kit myself?
A: It is possible if you have experience with 12V electrical systems and soldering. However, because these systems interface with your ignition, fuel pump, and security systems, we strongly recommend professional installation to avoid damaging your vehicle’s electronics.
Q: Is the remote start safe for manual transmission cars?
A: Many kits are compatible, but you must be extremely careful. You must always leave the car in neutral with the handbrake firmly engaged. Some high-end kits include sensors to prevent starting if the car is in gear.
