Mercury Grand Marquis Locksmith in Washington, DC

Mercury Grand Marquis lockout, keys and ignition service

The Mercury Grand Marquis is a sedan we see regularly on DC streets and in DC garages. Mercury used Ford PATS chip keys. Keys are cut and programmed the same way as their Ford equivalents.

Mercury Grand Marquis lockout

Locked out of your Mercury Grand Marquis? A technician arrives in 15–25 minutes anywhere in DC and opens it without damage. On sedans the most common lockout is keys left in the trunk. Many models disable the inside trunk release when the doors are locked, so we open the cabin first and then release the trunk. More about car lockout service.

Mercury Grand Marquis key made

If you lost your only Mercury Grand Marquis key, we cut a new one by code or by decoding the lock and program it at the car, so no tow is needed. Have your ID and registration ready. More about car key replacement.

Mercury Grand Marquis key programming

We program transponder keys, remote-head keys and push-to-start fobs for the Mercury Grand Marquis, add spares, and erase lost keys from the vehicle on request. More about key programming and key fob replacement.

Mercury Grand Marquis ignition repair and replacement

On turn-key versions of the Mercury Grand Marquis, a key that sticks or will not turn usually points to a worn key or worn ignition cylinder. We repair or replace the cylinder where the car sits and match it to your existing key when possible. Push-to-start versions have no cylinder; no-start problems there are usually the fob or its battery. More about ignition repair.
