Mercury Key Programming
Mercury uses Ford’s system, so if you have two working keys you can add another yourself onboard — no tools, no dealer. Down to one or zero keys, an automotive locksmith handles it (still well under dealer pricing). Standalone keyless remotes you can always program yourself. Find your model below.

Add a key yourself — the two-key method
If you have two keys that already work, Mercury’s onboard relearn adds a third in under a minute — no tools. (All keys lost, or only one working key? That’s an automotive locksmith.)
- Bladed/chip keys: insert the 1st working key, turn to ON (run), then OFF and remove — within 5 seconds.
- Insert the 2nd working key, turn to ON, then OFF and remove — within 5 seconds.
- Within 10 seconds, insert the new key and turn to ON — the security light confirms it’s programmed.
- Push-to-start (Intelligent Access): with the dash off, press START/STOP with working fob #1, then #2, then lay the new fob in the cupholder/backup slot and follow the message-center prompt.
Exact steps vary by year — message us your vehicle and we’ll send the precise sequence.
