Transponder Key

[tooleey]

Hello,
I have a 2007 Toyota Corolla. I want to get the on-board programming directions for making a duplicate ignition key. I have the key blank bought on e-bay, and I've had it cut. Also, I of course have the original working key, just need on-board programming instructions. If anyone can help me, it would surely be appreciated!


Thank-you,
Pat Riley

I believe only Dealer can program the key.

If you feel that only a dealer can do it, you must not be familiar with OBP (on-board programming)

The Toyota Electronic Control Module does not have programming modes without a pre-programmed key. If there is no key available that is already programmed into the module, the
module must be replaced. Toyota has limited the number of keys that can be programmed into any new (2002+) Toyota or Lexus vehicle. Only three working keys can be programmed
to a vehicle at any one time. If you try adding an additional key to a vehicle containing three Transponder keys, the vehicle’s On-Board computer will not accept the new key.

ADD A DUPLICATE KEY (Requires one working Toyota/Lexus Dealer Key):
1. Make sure all the vehicles doors and windows are closed.
2. Insert the Toyota/Lexus Dealer Key into the ignition.
3. Turn the ignition from ‘ON’ to ‘OFF’ five times.
4. Open and close the driver side door 6 times.
5. Remove the Toyota/Lexus Dealer Key and insert the new duplicate key.
6. Turn the ignition ‘ON’.
7. The new key will be registered after 60 seconds. The ‘THEFT’ light on the dashboard will go out, indicating successful programming.

I went through the same thing. I have purchased a key on e-bay and had it cut. Nothing works, I 've even tried a few locksmiths near me and I was told to go to the stealership. Who ever thought of this stupid key design should be smacked in the head.
