2005 Chevrolet Impala Parts Questions & Experts Answers

• Q: How to service and repair the Ignition Lock Cylinder on 2005 Chevrolet Impala?

  A: Service and repair processes for the ignition switch lock cylinder start by determining both key code and lock cylinder code specifications yet the vehicle operates using one standard key possessing the recorded five-character key code on its tag. Start key cutting using a blank key to align tumblers before using a wire brush or wire wheel to smooth edges and test the key's fit within the lock cylinder. Replacement lock cylinders arrive without tumblers or springs so customers must construct the components based on the mechanical key code. The operation of lock cylinder tumblers consists of matching tumbler notches to enable cylinder rotation. The ignition lock holding fixture (J 41340) enables Ignition Lock Cylinder core extraction through the start position while pressing the cylinder core retainer for core retrieval. A small flat-bladed tool removes the tumbler spring retainer so you can extract the tumbler springs and tumblers before recording their positions. Place tumbler springs above each tumbler in sequence then insert the tumblers into their designated positions and apply gm p/n 12346241 superlube or its equivalent as lubricant. Secure the tumbler spring retainer in place. Follow this sequence of actions: install the lock cylinder in the j 41340, stake the spring retainer and then lubricate the key slot before inserting the lock cylinder retainer spring with the lock cylinder retainer. Apply gm p/n 12345996 lubricant or equivalent to the lock cylinder housing detent pins and lock cylinder retainer followed by insertion of the Ignition Lock Cylinder before checking its rotation. To code alternative lock cylinders first determine the tumbler numbers and positions which require installation of the selected tumblers before executing either press-on or non-press-on capping steps to properly secure the lock cylinder door and cap.
