Question about 2003 Toyota Corolla
Don't have remotes anymore. Alarm keeps going off. Can't start car. How can we disable alarm?
I have a Code Alarm and needed to replace the battery. Funny thing is, I never knew I had the alarm until this problem happened (bought the minivan used). Town and Country 2006. Anyway, it turned out to be a real simple fix for me (after spending several hours messing with it).
Get some thick gloves on to make you feel safer (I'm not an electrician and always fear I'll shock myself when dealing with the car battery)
Unhook the negative on the battery (black). Place key in the ignition and turn to the point where you would normally be able to run all things electric without the car starting. Re-attach the negative cable. You may hear several clicks at this point as if the electric system is doing its job. Try starting the vehicle. Alarm should not go off and the vehicle should start.
I found that anytime I disconnect the battery, the car alarm problem returns. This includes if the battery died (and I don't disconnect it). Good luck.
If this works, then make sure the negative battery cable is tightened onto the battery so it doesn't come loose.
