Is it a factory alarm? If so, the only thing you can do is turn the key to the run position and let it sit for about 10+ minutes. That way it should start. Also, if it is a factor alarm, you need to take it to a dealer to have it repaired. They are the only ones with the proper test equipment to identify the problem.

Electrical problem
1997 Buick Lesabre 6 cyl Front Wheel Drive Automatic
The alarm system will sometimes go off intermittently while sitting in the driveway. The other issue deals with the SECURITY light. When the vehicle is in drive, the SECURITY light will appear on the dash and blink or stay on for several minutes. Does the alarm system need to be reset, or is this a more serious problem?

The PASS-Key(R) II system controls the "SECURITY" indicator. In normal operation, the PASS-Key(R) 11 module controls the lamp only when the ignition is ON. There are four PASS-Key(R) II system bulb modes as follows.
Bulb Check. When the ignition is first turned on, the SECURITY" indicator illuminates for approximately five seconds to indicate the system is operating correctly. Refer to the following bulb symptoms, if the bulb check does not operate.
Bulb Stays Illuminated and Engine Starts. If the "SECURITY" indicator stays illuminated after the engine starts, this is an indication that the PASS-Key  II module is reading an open, short or incorrect resistance value. Verify that the PASS-Key  II module connection at the base of the steering column is properly connected and that a good ignition key is being used.
Bulb Stays Illuminated and Engine Does Not Start. If the "SECURITY" indicator stays illuminated while and after attempting to start the engine and the engine does not crank or start, this indicates that the PASS-Key  II module has sensed an improper key value and has disabled the engine and set the disable timer. This specifically does not mean that the key sense circuit is open or shorted to chassis ground, refer to "Bulb Flashes and Engine Does Not Start." See: Testing and Inspection Remove the key from the ignition and verify that is the correct key code for the vehicle. The key code may be checked using J 35628-A and comparing the key code to that of other keys for the vehicle. After waiting approximately 3 minutes for the disable time to expire and the "SECURITY" indicator to go out, try to start the engine with a known good key with the proper key code.
Bulb Flashes and Engine Does Not Start. If the "SECURITY" indicator flashes once per second and the engine does not start, this indicates that the PASS-Key  II module sensed an open, a short or otherwise invalid (value matched none of the available 15 key codes) input from the ignition key resistor input. The PASS-Key  II module does not start the disable timer during this operation mode. This operation mode could also be caused by a malfunctioning power or ground circuits.

I replaced the driver side power window motor and had my key in the ignition to off and run position checking the motor. I must have deprogrammed something because I can't get the keyless remote to work. Doors, trunk etc. Please help. Ready to donate $25.00 via my credit card

The car alarm goes off in the middle of the night and this has been off and on for weeks. I had disconnected the horn and now reconnected it and it's doing it again. What could be the problem and how do I fix it?

While you may discover the problem with the scan previously mentioned, don't overlook the possible problem I've seen a number of other Buick, as well as other makes, owners have experienced, and that is a faulty key fob transmitter. They can make contact inside somehow, and set off the horn or car alarm without anyone touching the key fob, during the night or day. If you keep the key fob someplace out of range, to test it, you can rule it out or not, or pull the battery out. But sometimes you need it to unlock the doors, or it will set off the alarm, UNLESS the last action was to lock the doors with the KEY, instead of the key fob. Many cars remember the last cycle of how it was locked, and stay in that mode.
