Pulling out of driveway alarm went crazy. car cut off wouldn’t do anything ,after that charged battery now everything works but will not turn over to crank

Depends on vehicle, some will assume being stolen if battery voltage / amps drop too low and ECU or alarm system disables start / run. This is to prevent alarm being turned off by cutting battery wires. Normally needs a dealer with laptop and software to reset

How do I permanently disable a DEI Automate car alarm on our 1999 Acura Integra.

Just remove it. It shouldn't be too hard, take all the parts and harness out, reconnect any cut wires and wrap any exposed wires with electrical tape.

Put a new battery in my 97 jetta gt alarm went crazy finally got alarm to shut off by unlocking passenger door but now my car won't start or turn over how do I fix

You surged the electrical system. Had a 97 Golf that did the same and had to be towed to the dealer for a reset. They disconnect the battery again and had to reset everything plus probably replace a few fuses. I'd start with fuses connected to your starter and engine systems.

Hi, I had a start problem with my celica. tried to turn the car over and a constant clicking sound was made, however all lights were on and the radio was working.. thought possible starter problem,...

The problem is that your battery is extremely low. The repeated clicking sound is your starter relay trying to engage, then releasing again when the starter takes the remaining voltage available to try to turn. When the relay disengages, the starter can no longer take any voltage at all, so the relay again engages and the process starts over. This results in "CLICK, CLICK, CLICK, CLICK...." There simply is not enough power available to operate both the relay and the starter.

Your alarm system doesn't have enough voltage to function properly. It "thinks" that someone is trying to steal your car or is messing with your battery cables. It doesn't know the difference between low voltage from a dead battery and low voltage from somebody disconnecting wires. It is simply responding to the low voltage condition as it is designed to do. Fix the voltage problem and you will fix your security system. No need to reset anything.

Jump-start the car or replace the battery and get your charging system checked to make sure everything is functioning properly. It is possible that the battery is good but you have a bad alternator and the battery is low because it is not being charged.

Alarm system going off while driving or very quietly at other times for no reason .... sometimes with lights blinking... I have tried various configurations of locking, unlocking and locking, lockiing...

The backup battery in the alarm module corrodes and 'bleeds' over the little circuit board inside the alarm and makes it go crazy.

This module is on the passenger side under the front fender - sort of behind the headlight. I actually think it's easier to remove the headlight to get to it, but I think you can get to it by removing/bending the fender well plastic cover out of the way too.

Google the alarm module, it could be easier to replace the entire thing than to repair yours.

Alarm system not working

A friend of ours did some research and discovered it was the ECU (fuse?) that needed to be reset. We removed the ECU (which controls the cruise control, and "learns" the driving patterns of the driver and adjusts the fuel economy) and the car is running fine. To reset the ECU you need to remove the negative cable from the battery, turn the car to "A/C On" (don't crank the engine) for 10 seconds, then shut it off. Replace the negative battery cable. This should reset the ECU. The car does run much better with the new battery. The previous battery was the original and was approximately 6 1/2 years old so it needed to replaced anyway.
