Car Key Won’t Turn in Ignition
Ignition lock failure is not a common occurrence, but it can happen. This is usually apparent when you get into your vehicle, insert the key, and the ignition will not turn to start. In older vehicles, your key’d ignition system is entirely mechanical, from the lock cylinder all the way until the cylinder activates the ignition switch. On modern cars with keys, most are equipped with chip-keys that are theft deterrents, and must be properly mated to the car through software usually only available at the dealership.

Why Won’t Your Key Turn in Your Ignition?
Wondering why your key won’t turn in ignition? For many vehicles, once you remove the key, the steering wheel, if turned or bumped, will lock. This is made as a theft deterrent. Many folks though panic if they accidentally lock the wheel when leaving the car, then find the ignition appears to be locked when they re-insert the key and try to start it. To overcome this is simple – grab the wheel with one hand and wiggle back and forth while attempting to turn the key. The steering wheel will quickly unlock and the car will start.
If your car is not in park or neutral, you may not be able to turn the key. Even if the car is in park, manipulate the shifter a little bit to make sure the car really is in this gear. Then, try to turn the key again.
If you’ve tried the basics and the ignition cylinder is still locked, there are several other things you can check. If the car key is bent or worn out, it may not line up properly in the ignition to make the car start. If it is bent, you could use a hammer, preferably of rubber or wood, to gently flatten the key and try to start the car again. If the key is worn out, use your spare. You can also get a spare by contacting your dealership and provide them with your vehicle identification number (VIN) to get the key replaced. You can also have a new key made.
Check to make sure there is not any obstruction in the key cylinder. Use a flashlight to inspect the key cylinder. If the key cylinder has failed, you may see metal debris inside. Many times, the keys tumblers inside can get gummed up or stuck. To remedy this, take WD 40 or penetrating lubricant, and attach the small straw that comes with the can to the nozzle. Then, shoot a very small amount directly into the key hole. Next, insert the key in and out for about 30 seconds, which will work the penetrating oil into the tumblers and lubricate them. If the key still won’t turn after this, the next step would be to replace the ignition cylinder yourself, or contact a mechanic to help you out.
As stated before, most modern vehicles have an ignition key that must be programmed and properly mated to the vehicle. It’s important that you do research on your vehicle to determine whether your ignition key falls into this category, because sometimes, the keys programming or integrity could fail, leading to a key that the car simply does not recognize. In many of these cases, the dealership must be involved to reprogram the key. It doesn’t hurt though to also check with your local shops to see if there’s a specialty shop that can do this work.
