How to reset the security system after changing the battery.

Hello, a factory installed alarm system does not require any resetting. So if there is a problem and there are no aftermarket add on alarm systems or devices installed, there must be something else going on here. Check the maxi fuses under the hood for example to see if there are other issues present. Also, if the engine cranks, it's a whole different problem - as the battery and electrical system wouldn't be relevant here.
