RKE INTEGRATED KEY CASE AND FAST KEY CASE SERVICE PARTS KIT AVAILABILITY
This TSB supercedes TSB-09-42A-015, issued October, 2009, to update affected vehicles, add Outlander Sport and add FAST Key case part numbers. Changes are indicated by <.
PURPOSE
Remote Keyless Entry (RKE) integrated key case and FAST Key Transmitter case repair kits are now available. If the plastic parts of the key are broken or missing, but the key functions properly, use the appropriate service parts kit instead of replacing the entire key assembly. When replacing only the key case, it is not necessary to program immobilizer, RKE and 055 functions. For integrated RKE keys, once the electronic components are transferred to the new case, the key can be cut to the vehicle's key code.
The contents of each kit depends on the vehicle model and model year. Refer to the Kit Contents section of this TSB for details.
NOTE:
To prevent breakage during repair, please follow the instructions in "Features and Controls" of the owner's manual or Group 42A BODY of the service manual when opening the key case for battery replacement or other repairs.
