If you’ve considered adding a backup key fob for your Bronco (not Bronco Sport), you might want to do so before you’ve lost or damaged one of the two original fobs.
While keyless fobs like these often require dealer programming that can be extremely expensive, Bronco allows you to program up to two additional key fobs on your own - so long as you have the first two key fobs present. If you only have one, a trip to the dealer is likely your only recourse.
The process is outlined in the owner’s manual:
All you’ll have to do is source a compatible fob, follow the above steps, and if desired, have the physical key blank cut by a locksmith. I’ve received quotes of about $25 for blade key cutting. I have one fob set as a “valet” fob - key blade is uncut, and the key itself is programmed with all MyKey functions activated.
While I concede sticking with OE parts is probably your best bet for a reliable backup fob, if you’re feeling frugal, I will concede I’ve successfully programmed an extremely inexpensive non-OEM fob…
