2018 Tocoma Keeps Locking and unlocking

Hello I am having issues with my 2018 tocoma where the key fob only works sometimes and seems to be getting worse with cold weather. The truck also when driving or just sitting key in or out engine on or off will lock a few times up to 10 times in a row and sometime for five mins locking itself . The key fobs have been reprogramed and new batteries even used 3 different fobs only all with same result.

 

Maybe some help in this thread. Sounds like an issue with the keyless entry module.

Here’s another thread about oem install on 3rd gens. Maybe you can find the right parts or contact some owners via dm.

You might want to look to see where the other key fob is, the wife might be messing with you.lol. Kidding, I would think it’s a keyless entry module.

 

See if you can do a full OBD scan to see if any modules are reporting issues.
