Review on 🔑 Set of 2 Key Fob Keyless Entry Remotes for Ford, Lincoln, Mercury, Mazda - CWTWB1U331 GQ43VT11T CWTWB1U345 4-btn by Nelson Calafell

Purchased for my 2003 Mercury Sable sisters. It is very easy to program after watching YouTube videos. Simply insert the key into the ignition switch and cycle the ignition (do not start the vehicle) eight times within ten (10) seconds. Security begins to respond with locks. Press any button on the remote control (or on the remote controls you want to program - all this must be done during this program). You must have a reaction. When the car is finished turning. Remove the key and try your remote control(s). Everything should work. It is so easy. If you have any questions, just search the topic on YouTube. Good luck and ride.
