If you are not going to drive your vehicle for 25 days or more, remove the black, negative (-) cable from the battery. This will help keep the battery from running down.

Sometimes after I put my 2000 Buick Regal LS in Park and turn off the engine the ignition switch not the key gets stuck in the on and acc position. What causes this to happen?


Replace ignition switch (the tumbler portion) seems like its hanging up, and you shouldn't be able to remove the keys unless the switch is off.The park safety switch possibly. This switch tells the vehicle its in Park. Hope this helps.

Key stuck in my 2006 Buick Lacrosse I can start and drive the car but can't remove the key after turning off the engine without pushing the release button which is at the bottom of the steering colum. I do know that I have a bad battery and if i don't drive the car couple of days then it goes dead. Advance auto tested the battery and told me that it's a bad battery and gives 13volts output instead of 12v. Also, the anti theft red light on the dash is gone dead and it's not blinking any more. How do I reset that? Thanks


bad battery and if i don't drive the car couple of days then it goes dead ??? It's not the battery , you have a parasitic draw on the electrical system , that is what is draining the battery . Could be the instrument cluster .Watch this video . What's giving out 13 volts or when ? With the engine running hooking a volt meter to the battery the voltage should be 13 - 14 volts , depending on the load on the electrical system.

Does the vehicle have column or floor mounted gear selector ? Both have a safety feature Electronic Park Lock (EPL)/Ignition Lock Cylinder Control Actuator:
Electronic Park Lock (EPL)/Ignition Lock Cylinder Control Actuator: If the vehicle is equipped with automatic transmission and a floor mounted console gear shift, it has an ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in any position other than PARK and the vehicle may still be moving. The column ignition lock system consists of an ignition lock cylinder control actuator, and a park position switch that is located in the automatic transmission shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the vehicle transmission is not in the PARK position. If vehicle power is lost, and/or the transmission is not in the PARK position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.
Linear Shift Assembly: If the vehicle is equipped with a column mounted gear shift, it has a linear shift assembly on the steering column. The linear shift assembly has a cable that runs from the linear shift assembly to the ignition lock cylinder case. The purpose of this cable is to prevent the ignition key from being turned to the OFF position when the transmission is in gear and the vehicle may still be moving. The linear shift assembly cable contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the vehicle transmission is not in the PARK position. If vehicle power is lost, and/or the transmission is not in the PARK position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.

05' magnum keys stuck in ignition


It is possible that your problem is with the shift lock actuator. Charge the battery up. For safety sake charge the battery outside the car. If your ignition is on you don't want to hook up jumper cables. If you do it wrong you can spike the computer. Once you have a strong battery put your trans down in to low and then firmly back into park. The shift lock mechanism is meant to keep you from starting the car without putting your foot on the brake, but if it fails it can be engaged and not let you go back into park. Use a test light to check all your fuses if it still will not work. If that does not do it, start it in neutral and take it to the garage.

Hope that helps.

If the battery is dead, the shift interlock solenoid will not disengage the gear shift mechanism. You have to have sufficient current through the brake switch to disengage the interlock. Charging or replacing the battery should do it. Hope this helps
