Subject: | Theft Deterrent Module and Key Replacement |
Models: | 2007 Chevrolet Caprice, Lumina (Export) |
Previously when replacing the Theft Deterrent Module on a VE or WM vehicle, the transponder keys would also need to be replaced as it was not possible to reprogram the original keys to a new TDM.
As of TIS 2007/05, the original transponder keys can be retained when a new TDM is installed.
After installing the new TDM, perform Service Programming (SPS) of the TDM. Then program the original transponder keys using a Tech 2®
DO NOT replace the original transponder keys when replacing the TDM.
