Successful SC430 Key Programming

There is a lot of folklore, myths and procedures that work on some cars but not on others so it's up to you to try them until something works; or just give up. but in any case, you need a master key to succeed.

+1, without the master key there can be no success

If there is an inexpensive way to get a new shell, that would be nice, (it's broken down where the little bitty screw holds the halves together) but I'm not going to spend $100 in this economic climate when free tape will do the trick.

Well, it looks like the cheap eBay solutions work just fine.

I cut my flip key down to 38mm (it's long enough for the LX's) if for no other reason than aesthetics when it's in the ignition. Davenport Motors cut it for me for $0.00 (cool!).

Re: programming with the master, remember that you also have the card key, which is a master key.

Since I hadn't tried it before, I attempted to start the car with my broken key (no transponder) yesterday. The starter cranks, but it won't start, so apparently it disables the ignition, not power to the starter and other systems. Just FYI.

Davenport charged me $20 to cut my new key today.
At least I have one OK key now !!!

wow..that's a steal! Wish I would have thought of them back when I paid $60 at Park Place in 2006!!!
