To reprogram the transponder on a 2003 Mercury Sable, you'll need a working key and the vehicle's ignition system. Start by inserting the working key into the ignition and turning it to the "On" position without starting the engine. After about 10 minutes, turn the key back to the "Off" position and repeat this process two more times. On the third cycle, turn the key to the "On" position and then quickly insert the new key within 10 seconds to program it.
