    Try locking all the doors and unlock with the key from outside.

    GM passlock security issue. Put the key in the ignition, turn it to on or run and wait about 15 minutes until the light stops blinking. Do not turn the key to off, just start the car. If it continues you will need a new ignition switch.

    Try this to reset the pass-lock security system.

    This is free and all it takes is about 35 minutes of your time. If it doesn’t work, all you are out is a little bit of your time.

    First. make sure the battery is fully charged. If you have automatic headlights or daytime running lights disable them and it will help save your battery power. You should find instructions for this in your owner’s manual. You could park the car in the sunlight which would not activate your head lights on most models.

    Turn off all of the vehicle accessories. Roll down the windows. You roll down the windows just in case your doors lock while resetting your pass-lock security system.

    Place the key in the ignition. Turn the key to the run position but don’t start the engine. Don’t use the accessories position as this will not work.

    Leave the ignition in the on position for 10 minutes. At the 10 minute mark the security light will flash.

    When the security light flashes turn the ignition off.

    Wait a minute

    Repeat these steps two more times. Do not start the engine or place the ignition in the accessories position or you will need to start over from the beginning.

    After the third time of doing this your security system should be reset.

    Most buicks are VATS, not PassLock. Call a locksmith.
