Question:

If I replace my car battery, do I have to re-programm my keyless entry remotes?

I need to replace my battery soon.

sweet, that answers my question also.... I have to push the button a few times to get it to work

 

I am talking about replacing my car battery. Sorry.

 

I even replaced the battery in the keyless key chain thing and still didn't need to reprogram it.

Them there Toyota engineers is some smart fellers.

 

should have read closer...lol

Thanks for the info Eric

 

Maybe replace the battery. Or the button is worn out.

 

The remotes have their 'serial number/code' stored in EEPROM on the remote. EEPROM is non-volatile (it stays when power is removed)... ditto for the settings in the vehicle for the alarm. You can replace both batterys and not have to reprogram.
