Replacement 80 Bit Transponder Ignition Car Key fits H92 H84 H85 (Guaranteed to Work) Ford Lincoln Mercury, Set of 2

These worked great at a great price. Easy to program and turn well in the ignition after being cut for my key style. Saved a bunch vs the dealer key!

Worked for my 05 Aviator, programmed using Forscan.

They worked!

I bought these specifically for a 2002 Ford Ranger, which is listed as compatible. The keys I received had a small dot stamp. Per the locksmith, this indicates either a bad transponder chip, or... I forget the second indication. The upshot is, it did NOT work. When attempting self-programing, I got a rapid blink instead of a steady 5-second-on light. A rapid blink means the key is not compatible. I had to buy keys from the locksmith stamped with an "SA" instead of a dot. I've learned my lesson. It's a shot in the dark if a third-party key will work with your car. This is actually the 2nd time I've attempted to order a key (first time wasn't from Amazon), and both times I got incompatible keys. Next time I need a car key, I'll get one from the knowledgeable local locksmith. Addendum: Older cars like my 2002 Ranger limit you to a max of four programmed keys. Even if the key you buy is compatible, if extra keys have been made at anytime in the past, once all four memory slots are used, you cannot add any new keys without first clearing memory and reprogramming back in your existing and new key(s). This takes someone with the right OBD plugin equipment to do it, like a locksmith. This could also explain why some people haven't been able to self-program keys on their own.

Key worked great after getting it cut and programed no issues

Got cut at local hardware store. Only had one working key. Used forscan to program these. Both worked. Had to program one twice before it took but now I have 3 working keys.

Work perfectly. To prepare these keys for yourself you need to get them cut at either a Home Depot or Lowes, just have them cut it as the non-transponder version of the key. You then need to get a laptop with FORSCAN and the appropriate adapter, there are tutorials for this on youtube. you will also need the extended license for the Forscan software, you can either get a 2 month free trial by emailing them or buying a 1 year license for $12. One more thing, programming takes a little while as it has a lockout time interval to avoid someone just walking in your car and programming a key in 30 seconds. The interval is 12 minutes, which means 12 minutes that your car is running just off the battery. If you have a weak battery id highly recommend either replacing it or putting on a battery charger while you're programming, if the battery dies while programming you can potentially brick your entire PCM.

The keys worked perfectly as long as I had two original keys!
