The factory alarm/keyless entry on my 97 4runner just stopped working out of the blues. I thought it was the key fob (remote) that needed battery but neither of the two works. Also, normally the doors would lock when you start the engine (if all doors are closed) and unlock when you turn the engine off. I have checked (voltage) all the fuses under the steering wheel and they all seem to be ok. I have also spot checked are few under the hood. I have also checked (visually) to make sure that were was no loose connectors on the black box beneath the driver's seat.

Anyone has any ideas what could be wrong or have seen this before?

Not sure if this will help, but the other day I left the window down with less than a half inch gap because of the heat. It rained and there was some water settled on the driver's door handle. Could this have caused it to eventually stop working? I spent all day yesterday searching for someone with the same problem but they all seem to be different.

Thanks.
