I use a RW4 for duplicating and recently acquired a TKO for programming. Also I do on board programming (OBP)whenever I can--especially on keys like the GM B111 PT (OBP A or C).
My first job with the TKO was a failure on a 06 Toyota Corolla. I cut a working key from the customer's mechanical key. The customer did not have a transponder key for this transponder equipped car. I bought the correct key for the car--the Strattec STR-5910834 which corresponds to the Ilco ILP-TOY44D-PT.
I got an initial error message "key not recognised". I cleared the immobilzer, which got rid of the error message. I got a "key copied" or "key stored" message. But the car wouldn't start. I tried the procedure in the TKO "tips" which is put the key in the ignition and turn to start and then to off--five times--then remove the key from the ignition and then put it back in and start the car. But the car still didn't start.
I'd be interested in any comments.
