Treasure Coast Locksmith provides ignition switch replacement services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. Ignition switch replacement is different from ignition cylinder replacement - the switch is the electrical component that activates when the key is turned, while the cylinder is the mechanical lock. Both may need replacement together when failure occurs. Typical $245-$545 depending on brand.
The ignition switch is the electrical component of the ignition system that activates when you turn the key. It's physically separate from the ignition cylinder (the mechanical lock that accepts the key). Both components can fail independently, and both can require replacement when failure occurs.
When the ignition switch fails, you might see symptoms like the key turning normally but the engine not cranking, accessories not working when the key is in the "on" position, the starter not engaging, or intermittent electrical issues. These are different symptoms from ignition cylinder failure (key won't turn, worn cylinder, seized mechanism).
Treasure Coast Locksmith replaces ignition switches on all car brands, typically in conjunction with cylinder replacement if both have failed together. The switch and cylinder are physically connected and replacement is often easier when done together. Typical job runs 90-180 minutes including new key cutting and programming.

Ignition switch versus ignition cylinder
Ignition switches and ignition cylinders are often confused but are actually separate components with different failure modes. The cylinder is the mechanical lock you insert the key into - the part you can see from the driver's seat. The switch is the electrical component behind the cylinder that completes the circuit when the key is turned.
When you turn the key, the cylinder rotates, mechanically operating the switch. The switch then completes different electrical circuits at different rotation positions (off, accessory, on, start). When the circuit is complete, the starter engages, accessories power up, and the engine cranks.
Cylinder failure typically shows as mechanical issues - the key won't turn, the cylinder is seized, the cylinder wobbles, or a key breaks inside. Switch failure typically shows as electrical issues - the engine doesn't crank even though the key turns, accessories don't work, or electrical problems in the ignition circuit.
When one fails, the other is often worn too. For that reason, we often replace both components together during a single service call. This is more cost-effective than replacing them separately weeks or months apart.
Typical combined replacement 120-180 minutes onsite including new key programming.

Ignition switch tips
- Don't ignore intermittent starting issues - they usually indicate switch failure in progress.
- Keep heavy keychains off your ignition - weight accelerates switch and cylinder wear.
- Replace ignition switch proactively if the car is high-mileage and showing symptoms.
- Don't force a key that won't turn - could damage both cylinder and switch.
- Document ignition service for warranty and future reference.
- For European luxury cars, ignition switch replacement can be complex - choose a locksmith with brand experience.

Ignition switch FAQs
Common questions about ignition switch replacement.
How much does ignition switch replacement cost?
Switch alone: $245-$395. Combined switch and cylinder replacement: $345-$545. European luxury brands: $445-$745.
All include new key cutting and programming.
Is an ignition switch different from an ignition cylinder?
Yes. Cylinder is the mechanical lock you insert the key into. Switch is the electrical component that completes circuits when the key turns.
Both can fail independently and sometimes together.
What are the symptoms of ignition switch failure?
Key turns but engine doesn't crank. Accessories don't work when key is in 'on' position. Starter doesn't engage despite key turning.
Intermittent electrical issues in ignition circuit.
Can you replace an ignition switch mobile?
Usually yes. For most cars the switch is accessible from inside the vehicle and can be replaced without removing the steering wheel. For some brands and models, shop service may be faster.
Do you need to replace the cylinder and switch together?
Not always but often yes. If one is failing, the other is typically worn and will fail soon. Combined replacement is more cost-effective than separate service calls.
How long does ignition switch replacement take?
90-180 minutes including diagnosis, replacement, new key cutting, and programming. European luxury brands may take longer.
Will the new switch work with my existing key?
If just the switch is replaced, your existing key should continue to work. If both switch and cylinder are replaced, a new key is required (we include it in the service).
Can you replace ignition switch on European luxury cars?
Yes. BMW, Mercedes, Audi, Porsche, and other luxury brands. Replacement is more complex due to integrated immobilizer systems but within our scope.
What if my car is a push-to-start (no cylinder)?
Push-to-start vehicles don't have traditional ignition cylinders, but they do have electronic ignition switches (sometimes called ignition modules or start button modules). These can fail and be replaced. Different procedure than mechanical ignition switches.
Does ignition switch replacement require dealer tools?
For most cars no. Our Autel IM608 Pro and standard locksmith tools handle most ignition switch replacement. For some European luxury brands, specialty bench work may be needed.
Is ignition switch replacement covered by car warranty?
Sometimes. For cars under original warranty, ignition switch failure may be covered. For older cars out of warranty, owner pays.
Check your warranty status before committing.
How do I know if I need switch or cylinder replacement?
We diagnose onsite. If the key turns normally but electrical issues appear, it's typically switch failure. If the key doesn't turn or turns with resistance, it's cylinder failure.
Both common on high-mileage vehicles.
