Vehicle Identification Is Key
Before searching for a Door Lock Kit, it is essential to correctly identify your vehicle. The Mercury Monterey was a full-size car produced by the Mercury division of Ford, but its production ran in two separate periods. The original car line was manufactured from 1952 until 1974. The name was later brought back for a minivan model produced from 2004 to 2007.
The Mercury Monterey was not manufactured between 1986 and 1990. Any listings for parts for a 1986-1990 Monterey are incorrect. If you own a Mercury from this time frame, it is likely a different model, such as the Grand Marquis, Colony Park, or the Sable, which was introduced in 1986.
Common Door Lock Problems in Late 1980s Mercury Vehicles
While no specific information exists for a 1986-1990 Monterey, other Ford and Mercury vehicles from that era, like the Crown Victoria and Grand Marquis, experienced common door lock issues. These problems can give you an idea of what to look for on a similar-era vehicle.
- Sticking Latches: Old grease and accumulated dirt inside the door latch mechanism could cause it to stick, especially in cold weather.
- Power Lock Failure: On models with power locks, the actuators or the relays within the door module were known to fail. This could result in one or all doors failing to lock or unlock electronically.
- Broken Wires: The wires that run from the car's body into the door can become brittle and break over time from the repeated motion of opening and closing the door, leading to power lock failure. 🎬 Watch a diagnosis and repair of power door locks.
- Faulty Fuses: A simple blown fuse could be the reason power locks stop working.
Confirm Your Model
Before ordering parts, double-check the vehicle identification number (VIN) and the compliance plate, usually located on the driver's side door jamb. This will confirm the exact year and model of your Mercury, ensuring you purchase the correct parts.
Choosing an Aftermarket Door Lock Kit
Since no parts are made for a 1986-1990 Monterey, you must first identify your actual vehicle model. Once you have the correct model (e.g., Grand Marquis), you can look for aftermarket parts. For vehicles of this vintage, OEM (Original Equipment Manufacturer) parts are often discontinued. Aftermarket brands become the primary source for repairs.
For a similar vehicle like a 1990 Mercury Grand Marquis, you can find aftermarket door lock cylinders and repair kits. Brands like STRATTEC are known suppliers of lock components for many Ford and Mercury vehicles. Power door lock actuators are also widely available from various aftermarket brands.

Frequently Asked Questions
Why can't I find a door lock kit for my 1987 Mercury Monterey?
You cannot find parts because the Mercury Monterey was not produced in 1987. Production stopped in 1974 and did not resume until 2004. You likely have a different model, such as a Mercury Grand Marquis.
My power locks make a noise but don't work. What's the problem?
This often points to a failing door lock actuator. The motor inside the actuator may be weak or have a broken gear, preventing it from moving the lock mechanism fully. It could also be an issue with the relay in the driver's door module.
