BUYER BEWARE!!! Bait and switch ### 2/5 — A jumbled mess *2026-04-21, version 1.15* I’m pairing two new keys with remote unlocks for a Toyota Corolla. The instructions on the insert that comes with the module lists commands and prompts that the app doesn’t have! The app bounces around, has touch buttons without a link (dead), and will lurch from one page to another without input. I eventually paired my keys without any idea - from the app - how that happened. I could never get the remote buttons to work. A mess. I paired both keys but the app says I paired 5! ### 1/5 — Does not work *2026-03-11, version 1.15* Could not get the device to pair with my phone. Do better. ### 1/5 — App was unsuccessful at pairing key and remote *2026-02-08, version 1.14* App was undone to pair multiple keys and remotes, and blade key pairing did not work despite my following instructions and my vehicle being on the compatibility list on Car Keys Express’ website. A car Key Express agent had me try pairing the key and remote separately, which was not in the app or EZ installer instructions, and that was also unsuccessful. Ultimately the app and spare key and remote I ordered did nothing useful for me. My advice to others is seek a different source for spare keys for your vehicle. ### 5/5 — Worked for 2012 Mazda *2026-02-06, version 1.14* This worked surprisingly well. I had to pair the transponder key (physical cut key) and the buttons part of the fob in two passes. The sequence it had me follow (including opening the door three times) felt like borderline voodoo, but it worked!! ### 4/5 — 2015 RAV 4 *2026-02-02, version 1.14* The instructions could be clearer. Once I got it all set up, it acted like everything was working, but then said it failed to pair the key. Tried pairing a second time with the same error message. Unplugged the module and shut the car up. Just tried the new key and it worked perfectly, so it did pair properly, but the app didn’t detect it. In short, I have a new working key, so I am not complaining. ### 1/5 — Don’t buying *2025-10-08, version 1.14* Please don’t buy this product or used this app if the process fail you will need get professional lock smith ### 5/5 — Confusing at first but it worked for me. *2025-10-05, version 1.14* It took a few tries. ### 1/5 — For one time Only *2025-09-12, version 1.14* Only one vehicle! You can’t use it for different vehicles Only one time use ### 4/5 — It worked for me. *2025-06-16, version 1.13* I purchased a fob and key assembly for my 2018 Honda crv ex. The instructions were confusing for sure. They said install the ez installer app which I did. Wrong, that app just lets you buy more stuff and something about storing key info in the vault. Luckily iOS knew I didn’t have the correct app when I connected the CarKeys express OBD installer. I needed an app called Key Genius which then worked to pair the key fob I purchased. ## Frequently asked questions about Key Genius ### What does the Key Genius app do?
