I've been searching like crazy to find instructions on how to program a key FOB for a '05 Tundra. We bought it as a demo and it came with no remotes. I bought the whole keyless entry system from e-bay just to use the remotes. Now all I need are the instructions. Please HELP!!!!

Is it a Double Cab or an Access Cab. They have different keyless entry systems. Is it factory (some distributor areas install aftermarket and not the factory option) - what is the FCC #?

It is a double cab. Factory system for all I know. The truck is out of town right now so I can't be any more specific. Thanks for your reply.

To add an additional remote on the DC factory system

Perform steps 2 & 3 Within 40 sec.
2. Press door lock control switch (for manual operation) 5 times to LOCK/UNLOCK at approx. 1 sec. interval.
3. Close and open driver side door
Perform steps 4 , 5, 6 & 7 Within 40 sec.
4. Press door lock control switch again (for manual operation) 5 times to LOCK/UNLOCK at approx. 1 sec. interval.
5. Insert key into ignition key cylinder.
6. Turn ignition switch from LOCK to ON and back to LOCK at approximately
1 second intervals, 1 time (This sets ADD Mode)
7. Remove key from ignition key cylinder.
Within 3 sec, Body ECU automatically performs power door LOCK-UNLOCK operation to inform which mode has been selected. (1 LOCK-UNLOCK)
Perform steps 8 & 9 Within 40 sec.
