Programming for a 2003 to 2005 Toyota 4 Runner

When

Remote transmitter added or replaced.
System malfunction.

How

Driver's door open, key removed from ignition switch.
Within 5 seconds:
Insert and remove the key from the ignition switch twice.
Within 40 seconds:
Close and open driver's door twice.
Insert and remove the key from the ignition switch.
Within 40 seconds:
Close and open driver's door twice.
Insert the key into the ignition switch and close the driver's door.

Switch ignition ON and OFF once to program a remote transmitter code whilst
retaining the original codes or twice to program a remote transmitter code
whilst erasing the original codes. Three times to check how many remote
transmitters are currently registered or five times to erase all registered codes.

Remove key from ignition switch:
System should now lock and unlock vehicle once, twice or five times
depending which mode has been selected. One to four times, slowly, to
indicate number of remote transmitters registered.
Within 40 seconds:
Press and hold LOCK and UNLOCK buttons simultaneously for 1.5 seconds -
Within 3 seconds:
Press LOCK button.
System should now lock and unlock vehicle once to confirm registration,
twice to indicate registration has failed.
Within 40 seconds:
Repeat button procedure to program remaining remote transmitters.

NOTE: To exit programming mode: Open driver's door.

NOTE: A maximum of 4 remote transmitters can be programmed.


It may take a few tries and the timing must be very accurate to work but with a little patience it is easy.

I spent 3 days taking it places (battery shop, locksmiths, techie friends, etc. NONE have worked for my 2000. Then I just put my old fob guts into a new case and went on.... for awhile. Now I am told my remote is dead, new batteries do not help, so I purchased a new one on ebay. No luck, revisit of the frustration. Do I really have to pay the Stealership the $70? Someone said in earlier post the they did not think the 2000 was programmable. Can anyone else confirm this? Why?

(Sorry for the non-politically correct term in first sentence, just frustrated and no other term fits as well)

I get the confirmation "System should now lock and unlock vehicle.." after step 7, but nothing past that. Also working with new transponder key from dealership, and not a key fob remote. Thanks!

Is it possible to re-program the key fob to work with my new 4runner?


If possible does this have to be done at a toyota dealership? I appreciate any insight that you all may provide!

BTW I am new to this forum, so forgive me if this has been posted.
