2000 Chevrolet Impala Ignition Lock Cylinder Parts and Q&A

• Q: How to service and repair the Ignition Lock Cylinder on 2000 Chevrolet Impala?

  A: Initial work on the Ignition Lock Cylinder repair process starts with programming the new lock cylinder components as well as the pcm along with the bcm to receive their matching rpo information before applying learn procedures. During bcm replacement the passlock sensor data code automatically learns but a new fuel continue password requires learning by the existing pcm. When a pcm is replaced it learns the incoming fuel continue password through the password message it receives. To change your password, you must complete the learn procedure another time. Previously installed programming control modules need to undergo a learn procedure to gain access to the vehicle's current password. When performing the 10 minute re-learn procedure after replacing lock cylinders or passlock sensors or bcm or pcm mechanics should connect the tech 2 diagnostic tool to request information under service programming then remove the tool from the vehicle to connect it at a techline terminal and select theft module re-learn. After turning on the ignition with the engine off select vtd re-learn from the tech 2 interface. After approximately 10 minutes of idle time the security indicator will shut off which signals the vehicle is prepared to learn passlock sensor values and passwords through the Ignition Lock Cylinder transition between off and crank. The learning process ends by switching off ignition then waiting five seconds before turning on the engine. A scan tool can be used to remove all stored dtcs. During the 30 minute relearn activity users should turn on ignition during engine shutdown followed by an attempt at engine startup before allowing the key to switch to on position. The security telltale will need approximately 10 minutes to turn off. To perform a 30-minute relearn complete three cycles by turning off the ignition and waiting 5 seconds for each cycle. The vehicle reaches readiness for passlock sensor data code and password learning after the next Ignition Lock Cylinder transition between off and crank positions. Before starting your vehicle turn off the ignition but when you start the engine the vehicle will remember both the passlock sensor data code and the password you provided. A professional scan tool should be used to erase all stored dtcs.
