Key Programming Frequently Asked Questions (FAQ)
Keys programmed but only work in the backup slot
There are two portions to PATS Keys- the PATS functionality and the Remote Keyless Entry Functionality. A key that works only in
the back up slot likely had its PATS chip programmed to the vehicle but the frequency the key is sending lock/unlock commands
with may be wrong for the vehicle. Refer to page 2 to verify you have the correct key.
Replacement Key or additional key will not program
If a single replacement key or additional key is being programmed to the vehicle but the key programming fails, it’s likely the
replacement key is not correct for the vehicle. Because the vehicle started and ran with the original keys, this likely proves the PATS
module, wiring and antennas are okay. Refer to page 2 to verify the key you have is correct for the vehicle.
Security Access, Parameter Reset or key programming fails with a “Back End Server”
error message
The back end server error message encountered indicates that your computer was not able to verify your login or vehicle security
credentials with the IDS server. This is likely caused by the computers internet security settings not being set correctly. Refer to
page 15 for information on correcting the internet settings.
