Best investment for your car!
I'm loving my new keyless entry car lock! Super convenient and easy to install. No more fumbling for keys in the dark or worrying about lost ! I Highly recommend for added security and ease of use. Installation was a breeze, and it's been working flawlessly so far. Definitely worth the investment for the peace of mind alone!

Works great
Awesome product , I had a scion that had power locks but no keyless entry . It was fairly easy to install and even have it tied into parking lights flash when the car is locked and unlocked . All for less than the cost of one remote ! Comes with two remotes and control module .

Does its job. Took a lot of research.
I installed this on my 2007 F250 super duty. With a ton of research and some YouTube videos I was able to learn that my particular setup required 2 relays. I just now got it installed so we will see how it holds up but it works as it should. The instructions are only good for learning what wire is what. But apparently they are all that way. Photos are of the 2 relays and how they are wired for my particular vehicle minus the blue and the green wires. They should be wired to the white and white/black. Then the yellow and yellow/black go with the positive wires on each relay. Hope this helps someone!

BMW E36 series install
Instructions are basic, but the installation can be figured out with a little thought. BMW E36s typically have a wiring harness installed behind the glove box to support keyless remote locking and alarm modules. The systems works well and was a great price.

Not made for older trucks
It was too weak to unlock my trucks doors.

Worth the money
So cheap and works great. To be honest this is my second unit, but about 7-8 years of use out of the first one and it only took 2 minutes to unplug the old one and plug the new controller into the matching connector. For under $15 I have no problem with that.

Terrible wiring diagrams/ instructions.
I got this to work after working on it for MANY hours. The wiring diagrams (several possible) are not clear at all - wires that cross each other appear to be connected to each other as drawn, so you don’t know which are actually supposed to connect together versus crossing over. I also found after looking at other reviews/ comments and many other videos and on-line “general” instructions that I needed to use two 5-pin relays to making a polarity reversing circuit for my use. I am NOT an electrician or a mechanic, but I do MOST repairs myself on our 2005 motor home myself and consider myself pretty handy. But, this was literally an all day job with three trips to an auto parts store in the meantime (wrong relays purchased the first time, correct relays next, then fuses to replace spares I had on hand but went through quickly). I still need to replace a lot of wire connectors. The good: I did get it working and it’s quite inexpensive. The original “OEM” part is now obsolete and was listed for $250 at one place that said it was out of stock. The bad: As described above, poor instructions, non-standard wiring diagrams, more materials (relays, wire & connectors) may be needed.

Great upgrade for an older car with power locks!
I bought this for an old square body Chevy truck, that had power locks but not remote entry. It works great! I installed it inside the driver's side door panel. Take your time with the instructions and make sure you understand how it works before installing, as every car will be different. But it's great to have the convenience of remote locks in a 50-year old vehicle.

Range is good, too good
This works great. Simple to install once you locate the cars wiring. Range is good, too good I find lol.

Works, but terrible instructions
It works well but the instructions are so poorly given it’s terrible. If your car is negatively or positively triggered it’s fair easy to setup and I would use the top right diagram. My car ended up being a reverse polarity circuit so I had to get a couple of 5 pin relays and create a circuit to make it work.
