Review on 🔑 Set of 2 Key Fob Keyless Entry Remotes for Ford, Lincoln, Mercury, Mazda with Ignition Key (CWTWB1U331 GQ43VT11T CWTWB1U345 3-btn) by Patrick Bacho

First batch programmed 1/2 after cutting. Received an extended replacement and the following 2 keys appeared in the program. I was surprised that the number of keys did not increase in the last batch. Maybe they all have the same serial number or a different one used by the PATS system. Remember that you need 2 unique keys for your car to start. I had a real Ford key. Not sure how it works when you only had 2 aftermarket keys and they seem to be the same for the car. Another hurdle you face is finding someone to carve the keys. HD and ACE won't cut the "outer" keys, but they will sell you a blank one for $80. They then "program" your system by copying your key. Again, you need 2 unique keys, so the launch fails as well. Walmart finally nailed it, so call and make sure. The remote controls work well, but they don't have a button on the tailgate. It was definitely 90% cheaper than going to the expensive one, but you need the knowledge.
