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!

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.

Poor instructions but works well once installed
The system works well. The wiring diagram wasn’t great. Had to meter the pin outs to figure out what it was saying. It’s a NO or NC contact closure. The light flash is +12v diode protected but caused a battery drain in my car so I replaced with a relay. The system supposedly has rolling codes for protection and supports trunk/acct but no horn connection out of box.

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 .

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

Nice update for my car!
This product is awesome! I hated that my car didn't have automatic door locks. They are easy to install and use. They have a good range to lock/unlock, as needed. I highly recommend this product!

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.

Replacement for motorhome system that isn't avaliable anymore
I used this to replace the power lock control on my motorhome entry door. I needed replacement key fobs but the fobs nor the power control are no longer available. The manual that comes with this is is vague to say the least. But after about an hour I got it wired and installed. The unit and fobs are working great.
