SOURCE: cannot disable anti theft alarm driving neighbours mad

There should be a relay under the hood for the security system, if you can not find it, try jacking the front of the car up, it should have a sensor that tells it that it is being towed and should turn off, unless of course it has a bad wire that is grounding out.

Changed the battery and it set off the alarm. it seams like it activated a kill switch of some kind. is there a way to reset it?


You probably had your alarm set when you took out the old one. Just unlock your doors with your key fob, then disconnect the battery again for a few minutes and let it reset with the alarm off.

Truck won't start after anti-theft lock has been activated


Try disconnecting the battery for 10 seconds. I had a '98 that did that. It was the alarm that failed. I had to buy a new alarm module to fix it.

My battery went dead, and now that i try to jump start the vehicle, the alarm goes off and will not turn off. I cannot start the car at all


If this is an after market alarm, an alarm that was installed by someone other than a dealer there will be an in-line fuse under hood on the main power wire leading to the alarm horn. Usually along the firewall. Remove this fuse and you should be able to start the vehicle. The problem you are experiencing is the anti theft or ignition kill switch being activated because the alarm is detecting the lose of power as a Surge and triggering the anti theft circuit.

98 golf anti theft problem


Put the key in the driver door lock (or the trunk lock if you don't trust the driver's door- quite often on a vehicle of this age the wires break in the door and it won't electrically de-activate the alarm due to the broken wires)
Disconnect the battery.
Turn the key to the unlock position (toward the front of the car if using the driver or passenger doors) and release it- it will go back to centered, but will retain slack in the forward direction
Then reconnect the battery. You may get one beep out of the alarm horn. If it beeps continually, turn the key to unlock again.
As long as the alarm is de-activated it will not prevent the car from starting. If you are still having a problem it is not alarm related.

Good luck and keep me posted, be glad to help

98 lincoln town car wont start, the theft protection is activated


theft protection rsets itself. I have never seen a PCM go bad. Some just need a reflash which costs much, much less. You can get a used PCM if you really think you need one, at car-part.com. Page with asterisk is lowest price.

here's some info on antitheft. What's your red light doing on the dash when you turn on the key or try to start the car?

The passive anti-theft system (PATS) also contains the following components:
  • Theft indicator.
  • Encoded ignition key.
  • Passive anti-theft transceiver module.
  • Hybrid electronic cluster (HEC).
  • Powertrain control module.
  • J1850 communication network.
  • Lighting control module (LCM).
The passive anti-theft system (PATS) uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. This information can be found in customer literature such as the Owner's Manual.
PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 72 million billion combinations.
Each encoded ignition key must be programmed into a vehicle's hybrid electronic cluster (HEC) before it can be used to start the engine. There are special diagnostic service procedures outlined in the workshop manual that must be performed if the encoded ignition keys need to be replaced.
The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud, and contains an antenna connected to a small electronic module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the HEC.
The control functions are contained in the HEC. This module performs all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling engine enable. The HEC initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
PATS uses the powertrain control module (PCM) to enable or disable the engine. The HEC communicates with PCM over the J1850 network in order to enable engine operation. The HEC and the PCM use sophisticated messages in order to prevent a theft. The HEC communicates with the lighting control module (LCM), which controls the theft indicator.The HEC and the PCM share security data when first installed together that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The HEC also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic workshop procedures outlined in this service manual that may be performed if either the HEC or the PCM needs replacement.
All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working properly, the vehicle will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indictor will either flash rapidly or glow steadily (more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood, and trunk) and sounds an alarm.

1999 Continental will not start


I think the anti theft anewer is correct. I have an extra key for my '99 Lincoln continental that apparently doesnt have whatever "chip" it needs in it. If you try to use that key it cranks but won't start. I don't know if the key "chip" can fail or not. Maybe a quick conversation with a lock smith will shed some light on the problem.
