We've seen every ignition and key issue a vehicle can develop. Here are the problems our clients call us about most often.
This usually means the internal pins and tumblers inside the cylinder have worn past the point where a key alone can compensate. Forcing a stuck key can snap it off inside the housing, turning a simple repair into a bigger one. We diagnose the cylinder and replace it with a properly matched part so the key turns smoothly again.
A key that won't come back out after the vehicle is turned off is usually caused by worn or misaligned tumblers gripping the key too tightly. Leaving it stuck risks damaging both the key and the cylinder further if it's forced. We carefully extract the key and inspect the cylinder to determine if replacement is needed.
Losing every working key leaves a vehicle undriveable and requires originating a brand new key from scratch using the vehicle's identification number. Waiting too long can mean added towing costs if the vehicle is stuck somewhere inconvenient. We come to your location and cut and program a new key on-site for most makes and models.
A worn ignition cylinder that already grips the key too tightly is more likely to snap it under normal turning pressure. A broken key fragment left inside can prevent any key, new or old, from being inserted properly. We extract the fragment safely and assess whether the cylinder itself needs replacing at the same time.
This typically happens when the ignition cylinder fails while the steering lock mechanism is engaged, trapping the wheel in place. Driving is impossible until the mechanism releases, which can leave a vehicle stranded in an unsafe spot. We diagnose the cylinder and steering lock interaction and repair or replace whichever component has failed.
A key fob that looks correct but won't start the vehicle usually hasn't been properly programmed to the car's onboard computer. This is common after a replacement fob is purchased without professional programming included. We confirm the correct programming method for your specific vehicle and sync the fob so it works reliably.
When the key turns normally but the engine doesn't respond, the issue often traces back to a worn cylinder failing to make proper electrical contact rather than a dead battery. Continuing to try can wear the cylinder down further. We test the full ignition circuit to pinpoint whether the cylinder, switch, or another component is at fault.
Homeowners without a spare key or key code paperwork often assume a new key isn't possible, but most vehicles can still be originated from their identification number. Delaying this leaves the vehicle unusable in the meantime. We pull the key code directly and cut and program a new key that matches factory specifications.
Flickering dashboard lights while the key sits in the ignition often point to worn internal contacts inside the cylinder rather than a battery or alternator problem. Ignoring this can lead to complete ignition failure without warning. We test the cylinder's electrical contacts and replace the unit if wear is confirmed.
My key snapped off in the ignition on a Saturday morning. The technician from Ontario Door & Window Pros came out within an hour, extracted the broken piece, and replaced the whole cylinder right there in my driveway. Didn't have to deal with a tow truck at all.
The technician tested whether it was the cylinder or the switch before recommending any work, which I appreciated since I didn't want to pay for something I didn't need. Turned out to be the cylinder, and it was replaced within about two hours.
My car has a less common ignition system so the part had to be ordered. The technician was upfront about it and gave me a loaner key situation to get by overnight. Once the part arrived the install was quick and everything works perfectly now.
Lost my purse with my only car key inside. Called Ontario Door & Window Pros and they came out, verified my registration, and originated a brand new key plus replaced the ignition cylinder since it had also gotten worn from years of use. Back on the road same afternoon.
I called two other places first and both wanted to sell me a whole new ignition switch assembly. Ontario Door & Window Pros diagnosed it as just the cylinder and quoted me significantly less. Fixed it in about 90 minutes and the key turns smoothly now.
My key stopped turning at all while I was leaving work at night. Called for emergency service and a technician showed up within the hour, diagnosed it as a failed cylinder, and had my car running again before I had to worry about being out there alone much longer.
