How do you program the key FOB on a 2004 Toyota 4Runner?

Answer 1

I bought a remote from some place online (took 2 months to get it, so I won't recomend them) and they sent some instructions with it that didn't work. After some googling I found these instructions that worked.

1. Drivers door open, key removed from ignition switch

2. Within 5 sec insert and remove key from ignition switch twice

3. Within 40 sec close and open driver's door twice

4. Insert and remove key from ignition switch

5. Within 40 sec close and open driver's door twice

6. Insert key into ignition switch and close driver's door

7. Switch ignition ON and OFF once to program a remote transmitter while retaining the original codes. Switch ignition ON and OFF twice to program remote transmitters while erasing the original code. (Three times to check how many remotes are currently registered)

8. Remove key from ignition switch

9. System should now lock and unlock vehicle. Once, twice or five times depending on which mode has been selected. One to four times, slowly, to indicate how many remotes are registered

10. Within 40 sec press and hold remote transmitter's LOCK and UNLOCK buttons together for 1.5 sec and release.

11. Within 3 sec press remote lock button

12. System should now LOCK and UNLOCK vehicle. Once to confirm registration, twice to indicate programming has failed

13. Within 40 sec repeat steps 10-12 to program additional remote transmitters. Up to 4 remote transmitters can be programmed.

14. To exit programming mode open the driver's door

Note: pay careful attention to the timing of the intervals especially in steps 10 and 11. Holding the buttons too long or too short will cause the programming to fail. Multiple attempts might be necessary.
