This can be due 🎬 Watch this video if your key is stuck or won't turn. to worn-out tumblers inside the cylinder or a worn-out key. Sometimes, wiggling the steering wheel can help if the steering lock is bound, but if that doesn't work, the cylinder is a likely suspect.

A Note on Keys and Programming
Your Mercury Monterey uses a passive anti-theft system (PATS) with a chip in the key. When you replace the lock cylinder, you have two main options: get a cylinder that can be re-keyed to match your original keys, or use the new keys that come with the new cylinder. If you use the new keys, they will need to be programmed to your van's computer. Some Dorman kits include a simple programmer for DIY key learning, but this often requires you to have at least one original working key. If you've lost all your keys, you will likely need a locksmith or dealer to program them.

Frequently Asked Questions
Can I replace the ignition lock cylinder myself?
Yes, this is a DIY-feasible job for someone with basic mechanical skills. The process typically involves removing the steering column shrouds, inserting the key and turning it to the 'ACC' or 'ON' position, and then pressing a release pin to pull the cylinder out. However, dealing with the anti-theft key programming can add complexity.
Is the ignition lock cylinder the same as the ignition switch?
No. The lock cylinder is the mechanical tumbler you put your key into. The ignition switch is the electronic component behind it that the cylinder activates. While they are separate parts, a failing lock cylinder can prevent the switch from working correctly. It's important to diagnose the problem correctly to avoid replacing the wrong part.
Do I need to get new keys?
Not always. Some replacement cylinders are 'uncoded' and can be assembled with new tumblers to match your existing key. This saves you the hassle of reprogramming. However, many kits come with new keys that will need to be programmed to your vehicle's computer to start the engine.
Why won't my key turn? Is it always the lock cylinder?
Not always, but it's a common cause. First, make sure your steering wheel isn't locked against the steering column lock; try turning the wheel back and forth while gently trying to turn the key. Also, ensure the gear shifter is fully in Park. A very worn key can also be the problem. If these checks don't solve it, the issue is likely inside the lock cylinder.
