Ignition Repair vs Replacement in DFW: Which Do You Need?

First: Is It the Key or the Ignition?

Before you assume the ignition is broken, check the key. A worn or bent key can cause the same symptoms as a failing ignition — the key won't turn, or it sticks. Try your spare key if you have one. If the spare turns fine, the problem is the key, not the ignition.

If you don't have a spare, or if the spare also won't turn, the problem is likely the ignition cylinder. Here's how to tell what kind of repair you need.

Symptoms of Ignition Problems

Common signs your ignition is failing:

• Key won't turn — the most common symptom. Could be worn tumblers, a broken wafer, or a failing electronic switch
• Key turns but nothing happens — the electronic ignition switch isn't sending the start signal
• Key turns but the engine doesn't crank — could be the switch, the starter, or the immobilizer
• Key is hard to turn — feels sticky or requires wiggling. Worn tumblers are starting to fail
• Key gets stuck and won't come out — a broken park interlock or worn tumblers
• Car starts intermittently — the switch has dead spots that work sometimes

When Ignition Repair Is Enough

Repair (not full replacement) works for these issues:

• Worn tumblers — we can replace the individual tumbler pins without replacing the whole cylinder. Cost: $150-$200
• Stuck key — often a broken wafer or debris. We can clean or replace the wafer. Cost: $120-$180
• Minor electronic issues — sometimes the switch's electrical contacts just need cleaning. Cost: $100-$150
• Repair is faster (20-30 minutes) and cheaper, and you keep your same key

When You Need Full Ignition Replacement

Replacement is necessary for these issues:

• Severely worn or damaged cylinder — too many tumblers are worn to repair individually
• Broken cylinder housing — physical damage to the cylinder body
• Electronic ignition switch failure — the switch itself is dead, not just the mechanical cylinder
• After a break-in or theft attempt — the ignition may be damaged beyond repair
• Cost: $200-$400 including the new cylinder, labor, and key programming
• Replacement takes 45-60 minutes on-site

Can Ignition Repair Be Done at My Location?

Yes. Our mobile rigs carry ignition cylinders, replacement tumblers, wafer kits, and electronic diagnostic tools. We repair or replace your ignition on-site — at your home, office, or roadside. No tow required.

This is a major advantage over the dealership, which requires you to tow the car in. We come to you, diagnose the problem, and fix it where you're parked.

What Happens to Your Key After Ignition Replacement?

If we replace your ignition cylinder, the new cylinder comes with a new key. Your old key won't work in the new ignition. You have two options:

Option 1: Use the new key that comes with the cylinder (and get a spare made). Your old key no longer starts the car, but it may still unlock the doors if they use a separate cylinder.

Option 2: We can rekey the new cylinder to match your existing key, so you keep using the same key for everything. This adds $30-$50 but keeps things simple — one key for ignition and doors.
