Cadillac 2007 - Manual (Page 122)

See your dealer or a locksmith who can service
PASS-Key
® III+ to get a new key blank that is cut
exactly as the ignition key that operates the
system.
To program the new additional key do the
following:
1. Verify that the new key has a 1 stamped on it.
2. Insert the original, already programmed, key
in the ignition and start the engine. If the
engine will not start, see your dealer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed
and turn it to the RUN position within
five seconds of removing the original key.
5. The security light will turn off once the key
has been programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.
If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
® III+ system, however,
may not be working properly and must be serviced
by your dealer.
If you lose or damage your PASS-Key ® III+ key,
see your dealer or a locksmith who can service
PASS-Key
® III+ to have a new key made.
