Locked out of your Mercury?
Ford retired the Mercury brand in 2011, but the Grand Marquis, Mountaineer, Mariner, Milan and Sable are still around. A lockout on one of them is usually a simple job, and we treat older locks and seals gently. Tell us the model and where it's parked, and we'll quote it on the phone.
What to expect when you call
Proper entry tools
Coat hangers and slim jims belong in the past. Our technicians use automotive entry tools made to open a door without bending the frame or tearing the weatherstripping.
Quote before we drive out
Tell us the Mercury model, the year and where it’s parked. You get a quote on the phone, and that’s what you pay unless you ask us for extra work.
ID check up front
Before the technician starts on the door, we ask to see a government issued ID. It takes a few seconds and keeps us from opening a car for someone it doesn’t belong to.
Careful around the electronics
Modern car doors hold wiring, airbag sensors and window motors. We work slowly around them, and if your Mercury calls for a different approach, we say so before we start.
No hidden fees
The quote covers the lockout. If we find something else at the car, like a broken key stuck in the lock, we explain it and give you the price before doing anything about it.
Key lost instead of locked in
If the key is gone for good, ask about a replacement when you call. If it’s a key we can cut and program, the technician brings the equipment for it.
How does our Mercury lockout service work?
You call us
Call (855) 588-0198 and tell us where you are, what you drive and what happened. You get a quote and a realistic arrival time on the same call.
A technician heads out
We send a mobile technician to the address you gave us. If anything changes on our side, we call to let you know.
ID check first
Before any work starts, the technician asks to see a government issued ID.
Opening the door
The technician looks over the door and lock, then opens your Mercury with automotive entry tools, carefully and without forcing anything.
Keys back in hand
Once the door is open, you get your keys back and can check that everything inside is as you left it.
A final check
We make sure the locks on your Mercury work as they should before we leave, and you pay the price you were quoted.
Common Mercury lockout situations
Keys locked in your Mercury
The keys are on the seat or in the cupholder and every door is locked. Smart key cars try to prevent it, but a fob in a bag or a door locked by hand can still get past that.
Mercury key fob not working
A weak fob battery or a flat car battery can leave the buttons doing nothing. We open the door by hand, and from there you can check the fob battery or the car battery.
Mercury trunk lockout
Keys in the trunk, or a trunk that won’t release with the button or the fob. We usually get in through a door first and go from there.
Broken key in a Mercury lock
An old or worn key can snap off in the door lock or the ignition. We extract the broken piece and let you know whether the lock or the key needs attention afterward.
How we open a locked Mercury
Every Mercury from the late 1990s on uses Ford's PATS transponder key system. The Grand Marquis takes an eight cut key with a chip, Mountaineers and Sables use PATS keys too, and later Milans and Mariners came with remote head keys. Some, like the 2010 Milan, also have the SecuriCode keypad on the driver's door. Older door locks and linkages wear, so we leave the cylinder alone when we open the door.
Before you call: quick checks for Mercury owners
If your Mercury has the five digit keypad on the driver's door, the factory code is on a card that came with the owner's materials. If you kept a copy outside the car, try it first. Otherwise, look for a spare key.
Lost or damaged Mercury key?
What a replacement key involves depends on the year. Older cars take a plain cut key. Most cars built since the late 1990s have a transponder chip in the key, and many newer ones use a remote head key, a flip key or a smart key. The technician we send can cut and program many of these on site.

Can you still get keys for a Mercury?
Mercury keys are Ford PATS keys, so blanks are still easy to find. A new one needs cutting and programming to the car. Tell us the model and year when you call and we'll explain what's involved.
What should I do if my Mercury key broke in the lock?
Leave the broken piece where it is and don’t try to turn what’s left. We remove it with extraction tools, check that the lock still works, and talk you through a new key if you need one.
Which areas do you cover?
Our mobile technicians cover Maryland, Washington DC and Northern Virginia, working out from Silver Spring to Baltimore, Frederick and Prince William County.
