Disable anti theft system

Good morning,

Is the security light on after about ten seconds with the key on?

Do you have another key you can try?

You can try the key relearn so the key can relearn the password to the security system. There is no turning it off or bypassing the system.

Below is the procedure

STEPS

Important: Erase the passlockTM related Diagnostic Trouble Codes (DTCs) that are stored in the VCM/PCM. If there are any powertrain related DTCs, record these DTCs then refer to A Powertrain On Board Diagnostic (OBD) System Check. See: Computers and Control Systems > Initial Inspection and Diagnostic Overview

The following is the Auto Learn Procedure:
1. Insure the ignition key is in the ON position.
2. Clear all EVO/passlockTM module and VCM/PCM DTCs. Record and refer any VCM/PCM DTCs. Refer to A Powertrain On Board Diagnostic (OBD) System Check. See: Computers and Control Systems > Initial Inspection and Diagnostic Overview

3. Momentarily rotate the ignition key to the CRANK position (Do NOT start the vehicle), then release it to the RUN position (Do NOT key OFF in the process).
4. Wait 10 minutes. Observe the SECURITY indicator. Refer to the following list for the appropriate responses:
If the passlockTM sensor was replaced the SECURITY indicator will flash for the 10 minutes duration.
If the EVO/PasslockTM module was replaced, the SECURITY indicator will flash for a few seconds and then remain ON for the remainder of the 10 minutes duration.
If the VCM/PCM was replaced with a new programmed VCM/PCM and connected to the vehicle for the first time, the vehicle will start and this procedure may not be necessary.
If the replacement VCM/PCM was connected to any vehicle at any other time, even momentarily, the SECURITY indicator will flash for a few seconds and then remain ON for the 10 minutes duration.
5. The SECURITY indicator will transition from flashing to ON briefly to OFF after 10 minutes if remaining in the ignition ON position.
6. Turn the ignition switch to the OFF position and wait for 10 seconds.
7. Repeat steps 3-6 two more times. The new security code is ready to be communicated among the Passlock sensor, EVO/Passlock module and VCM/PCM. The new password is learned on the next ignition lock cylinder cycle from OFF to CRANK to ON (start attempt).
