How to reset car alarm after car battery replacement toyota corolla 1998 Car alarm keeps going off after I replaced the car battery and it won't start. I tried turning the key to the "on" position and pushing in the valet/reset button but that didn't help. Still beeping and not starting!

Hello,

yes sometime the security system can get mixed up when changing the battery. Disconnect the battery for 30 minutes. Then reconnect the battery, without trying to start the car lock the drivers door using the key. Let the car sit for 30 more minutes. Then unlock the door using the key and the car should start.

Here is a guide for more details.

Please let us know what happens.

Cheers, Ken
