it can be tricky to do its all in the timing of doing all the stages
I did this with my first key and at stage 7 i done it twice (to rewrite) and it worked perfectly.
To re-programme my second key, I used my first key throughout the sequence but with two differences. The first one was stage 7 again where Done the off-on-off just once (To add a key). The second difference was at stage 9. When I pulled the programmed key out from stage 7, I held down the lock button on the other key and then pressed the unlock on that same key the five times as it requested. This worked first time and it saved me taking my car to the lexus garage to be charged a fortune. If anybody has any problems with this let me know. I'm not an expert, by any means, but have just learned how to do this and won't ever forget.
