💡 Why We Recommend It
This kit is a life-saver for owners of older trucks or sedans that never had power locks. It comes with everything you need, from the control box to the actual mechanical parts that move the lock pins. It feels sturdy and the remotes have a satisfying click that lets you know the signal was sent.
What makes this the best aftermarket keyless entry system for most people is the total package. You don’t have to hunt for extra parts. Even though it requires a bit of wiring knowledge, the results are smooth and reliable for daily use.

💡 Why We Recommend It
If your car already has power locks but you just lack the remote control, this is a fantastic upgrade. It focuses on software and control rather than providing heavy actuators. It is very versatile because it handles the pneumatic locks found in older European cars just as well as standard electronic locks.
The added features like the car finder and window control make this feel like a high-end factory system. It is compact and hides easily under the dashboard, keeping your interior looking clean while adding modern functionality.

The Ejoyous system is the best aftermarket keyless entry system for those who want premium features without the premium price. It is incredibly simple to set up if you have basic wiring knowledge. The inclusion of two remotes is great for families or having a spare on hand.
We particularly like the feedback the system gives. Seeing your lights flash gives you peace of mind when walking away from your car in a dark alley. It is robust, handles daily wear well, and the buttons on the remote are recessed enough to avoid accidental presses in your pocket.

The BANVIE system stands out because of its smart automation. While most systems just let you lock and unlock manually, this one thinks for you. The foot-brake locking feature is a great safety addition, especially if you have kids in the back seat.
The remotes are 4-button transmitters that feel very professional. They aren’t flimsy plastic and can withstand being on a keyring with several other items. For someone who wants their car to feel a bit smarter, the BANVIE is an excellent choice.

- ✓ Remote Start Compatible: Can be integrated with remote engine start systems for comfort.

The hands-free proximity feature is what truly makes this the best aftermarket keyless entry system for busy people. Imagine walking up to your car with grocery bags in both hands and having the doors unlock automatically. It feels magical and works surprisingly well for an aftermarket kit.

This product is ideal for: heavy-duty users and parents who often have their hands full.
⚖️ Pros and Cons
✅ Pros
- Hands-free proximity unlocking
- Compatible with remote start
- Excellent range for larger vehicles
- Durable key fobs
❌ Cons
💬 What Customers Say

— Verified Buyer
6. BANVIE Aftermarket Keyless Entry System for Central Door Locks
🌟 Key Features That Stand Out
- ✓ Reliable Car Location: Dedicated button to make the car chirp or flash so you can find it.
- ✓ 21-Second Window Signal: Extra-long output ensures windows have enough time to fully close.
- ✓ Compact Transmitter: Slim remotes that won’t take up too much space in your pocket.
- ✓ Voltage Protection: Handles minor voltage spikes common in older 12V systems.
💡 Why We Recommend It
This version of the BANVIE system is built for the daily commuter. It is reliable, no-nonsense, and focuses on the features you use every single day. The 21-second negative output for window closing is particularly thoughtful, as some cheaper units stop the signal too early, leaving windows half-open.
It works seamlessly with both pneumatic and electrical systems, making it a safe bet regardless of what car you drive. The build quality of the control module is high, with weather-resistant casing that protects the sensitive internal circuitry from moisture or dust.
🎯 Best For
This product is ideal for: daily commuters who want a reliable, simple system that works every time.
⚖️ Pros and Cons
✅ Pros
- Very reliable window closing signal
- Slim and pocket-friendly remotes
- Strong signal even in busy cities
- Great price point
❌ Cons
💬 What Customers Say
“The window signal is perfect. Every other kit I tried cut out too early, but this one finishes the job.”
— Verified Buyer
“I like how small the remotes are. They don’t make my key ring look like a mess.”
— Verified Buyer
7. Aiuphing Universal Aftermarket Keyless Entry System and Remote Central Locking Kit
🌟 Key Features That Stand Out
- ✓ Anti-Theft Features: Advanced encryption makes it much harder for thieves to copy your remote signal.
- ✓ Code Learning Remotes: Easy to program extra remotes if you lose one.
- ✓ Compact Control Module: One of the smallest units available, fitting into tight dash spaces.
- ✓ Flashing Alert: Visual confirmation via car lights when locking or unlocking.
💡 Why We Recommend It
The Aiuphing system is the best aftermarket keyless entry system for those who prioritize anti-theft tech above all else. Its code learning feature is a standout, allowing you to pair new remotes without needing specialized professional tools. This makes long-term maintenance much easier for the average car owner.
It is a very simple “core” system. It doesn’t have a lot of flashy extras, but what it does, it does very well. The signal is crisp and responsive, and the tiny control box is a dream for installers working with modern cars that have very little empty space under the dashboard.
🎯 Best For
This product is ideal for: owners of smaller cars or those who want extra security against signal hacking.
⚖️ Pros and Cons
✅ Pros
- Excellent anti-theft security
- Easiest module to hide during install
- User-friendly code learning
- Very responsive signal
❌ Cons
💬 What Customers Say
“The small size was the only reason I could fit it in my convertible. It’s tucked away and works perfectly.”
— Verified Buyer
“Simple to set up and the anti-theft peace of mind is worth the extra few dollars.”
— Verified Buyer
Complete Buying Guide for Best Aftermarket Keyless Entry System
Essential Factors We Consider
When shopping for the best aftermarket keyless entry system, the first thing to check is compatibility. Most systems use a universal 12V power source, but you need to know if your car has electric or pneumatic locks. Pneumatic locks are common in older Mercedes or VW models and need specific timing to work correctly. You should also look at the range. If you park your car far from your apartment, you need a system that can punch through walls and distance.
Budget Planning
Budget systems are usually just control boxes and remotes. These are perfect if your car already has central power locking. If you have a car with purely manual locks (where you have to physically push the pin down), you will need a kit that includes actuators. These kits cost a bit more but are necessary for the upgrade. Also, consider if you want extra features like trunk release or window closing, as these can add a few dollars to the price but save you tons of effort later.
Final Thoughts
Adding keyless entry is one of the best upgrades you can give an older car. It makes the vehicle feel much more modern and significantly increases your daily convenience. Whether you want a simple lock/unlock remote or a full-featured automation kit, there is an option that fits your needs. Take your time with the installation, and you’ll enjoy a much smoother car experience for years to come.
Frequently Asked Questions
Q: Can I install these systems myself?
A: Yes, if you are comfortable with basic 12V automotive wiring. However, if your car has a complex anti-theft system or computer-controlled locks, you might want to visit a professional shop.
Q: Will these work on any car?
A: Most are universal and work on any 12V vehicle. The main difference is whether you need a kit with actuators or just the control box.
Q: Do these systems include a car alarm?
A: Most keyless entry kits do not include a loud siren. They focus on locking and unlocking. If you want a siren, you should look for a “Full Security System” or “Car Alarm Kit.”
Q: How long do the remote batteries last?
A: Most remote batteries last about 1 to 2 years depending on how often you use them. They usually use standard coin-cell batteries that are easy to replace.
