2001 Chevrolet Impala Ignition Lock Cylinder Parts Questions & Experts Answers

• Q: How to service and repair the Ignition Lock Cylinder on 2001 Chevrolet Impala?

  A: You must start your ignition switch lock cylinder service by reading the key and lock cylinder codes where the same key serves all locks and the five-character sequence exists on the key tag. Key cutting requires determining the mechanical key code and fabricating the blank key to reach the correct each tumbler position levels before smoothing the ends with a wire brush or wheel and checking the key's functionality in the lock cylinder. Customers can purchase replacement lock cylinders that lack tumblers and springs yet they require assembly based on the mechanical key code. The tumbler operation of lock cylinders succeeds when tumblers align their notches to enable cylinder rotation. When coding ignition lock cylinders operators should utilize the Ignition Lock Holding Fixture (J 41340) as a securing tool. To replace the core of an ignition lock cylinder start by inserting the key to the "START" position while pressing the retainer to extract the core. Securely position the tumbler springs by first using a small flat-bladed tool to remove the spring retainer before carefully recording the tumbler sequence. Place the tumblers in their coded sequence followed by adding a tumbler spring above each piece and applying Superlube GM P/N 12346241 or equivalent before securing the spring retainer. Proper installation should be verified first and then the J 41340 punch used to stake the spring retainer. The final step involves lubricating the lock cylinder core retainer slot prior to inserting the lock cylinder retainer spring and lock cylinder retainer. Use GM P/N 12345996 or equivalent lubricant to oil the lock cylinder housing detent pins together with lock cylinder retainer then place the lock cylinder retainer into position before inserting the ignition lock cylinder into its housing while ensuring the key allows for proper rotation. To work on other lock cylinders begin by establishing tumbler numbers and positions followed by tumbler installation then complete either the press-on cap procedure or non-press-on cap procedure to ensure proper seating and securement of all elements.
