Cannot re-program old keys on new ECU

Post by b2gallant » Sun Sep 08, 2019 12:50 pm

I replaced the ECU (PCM) in my 2001 Sable. The ECU was programmed with the Sable's VIN number by the company I bought it from, however, my original keys do not work. I tried re-programming the keys myself with my LAUNCH X431 V PRO Bi-Directional Scan Tool, but each time I try the tool says it cannot communicate with module. When I bought the tool it said that it is able to program keys.

The tool can communicate with the new ECU to do everything else, so I know the tool does work, it only fails to reprogram the keys.

Does anyone know of a scan tool that can perform this operation (less than $1200)? Or, proven procedure that will allow me to reprogram the keys on this new ECU?

Regards,
Bill

Couldn't you tow it to the dealer and pay them for less than $1200? Personally I don't mess with that stuff, it's not worth the risk.

You might want to look into ForSCAN to see if it will do what you want.
2000 Ford Taurus SEL (excellent car, sold to a friend)
1992 Mercury Sable GS (good car except for the tranny, sold)

Thanks for the reply!

Absolutely, I could tow it to the dealer for less. However, I work on my own cars (5 including the kids') and have been aiming to buy a good scan tool. In fact, I bought a scan tool that said it would re-program keys ($800), sent it back because it did not deliver what it claimed it would (could not program the keys).

Hopefully someone will know.

Thanks,
Regards.

Thanks to all of you who reviewed my issue and offered an opinion.

I could not re-program the ECU with my LAUNCH X431 V PRO Bi-Directional, but I could with the Autel MaxiDAS DS808K, took about 15 minutes. I did like the LAUNCH X431 scan tool, really nice tool, but it just could not do what I wanted it to do.

Regards
