It wouldn't bother me much, but it does not allow the remotes to work. Occasionally, like 1 of every 10 times, when I remove the key after driving, the lock and key works as designed and the remote works (no beeping when I open the driver's door). So I thought, maybe something was getting stuck in the lock.

More than likely this is an issue with the key reminder switch.

Basically, if the body computer is being told that the key is in the ignition then it is going to disable the locks with the remote so that you don't lock the key in the vehicle.

I am attaching the info below on this switch. Please run through this info and let us know what questions you have and what turns up.

Thanks
