Car ignition problems are one of the most disruptive automotive emergencies - when the ignition doesn't turn, you can't drive the car anywhere. And towing to a dealer for ignition work is expensive and time-consuming. Mobile ignition repair is faster, cheaper, and doesn't require a tow.
Ignition issues fall into several categories. Seized cylinders that won't turn at all (often from worn internal parts or corrosion). Worn cylinders where the key turns but with resistance or intermittent failure.
Broken keys stuck inside the cylinder. Damaged cylinders from forced entry attempts. And simply old cylinders that have reached the end of their mechanical life.
Treasure Coast Locksmith handles all ignition repair scenarios onsite. For worn cylinders, we sometimes can rebuild with fresh pin tumblers. For seized or damaged cylinders, we replace with matching new cylinders and cut new keys to match.
Most ignition jobs finish in 60-120 minutes onsite.

Types of ignition failure and repair options
Car ignition failures happen in predictable patterns. Understanding which type you have determines the right repair approach.
Worn cylinders are the most common failure after 100,000+ miles of use. The pin tumblers inside the cylinder wear down from repeated key insertion, eventually becoming loose enough that the cylinder either won't turn reliably or turns with excessive resistance. Worn cylinders can sometimes be rebuilt with fresh pin tumblers ($195-$295 labor plus $45-$95 parts), but often the entire cylinder needs replacement.
Seized cylinders won't turn at all, often because internal parts have corroded, broken, or shifted out of alignment. Seized cylinders almost always need replacement rather than repair. The key sometimes breaks in the process of trying to force a seized cylinder.
We extract any broken pieces and install a new cylinder matching the original specification.
Damaged cylinders from pry attempts or forced entry need replacement. The exterior housing may look intact but the internal mechanism is compromised. Replacement is the only reliable fix.
Different brands have different cylinder replacement procedures. Honda and Toyota often require removing the steering wheel for cylinder access. Ford and Chevy typically allow cylinder removal through the dashboard without steering wheel removal.
BMW and Mercedes have complex cylinder assemblies integrated with the immobilizer module - sometimes the entire EIS or CAS module needs replacement along with the cylinder. 
How ignition repair works
Phone diagnosis
Call (772) 758-1322. Describe the symptoms - won't turn, turns rough, key stuck, etc.
Onsite assessment
Technician verifies the exact cylinder issue and scope of repair.
Repair or replace
Rebuild with fresh pins, replace with matching cylinder, or extract broken key.
New key and programming
Cut and program a new key to match the repaired or replaced cylinder.
Ignition maintenance tips
- Never force a key that feels wrong - worn keys or sticky cylinders need immediate attention, not forcing.
- Lubricate ignition cylinders annually with dry graphite to prevent wear.
- Replace worn keys before they break - cut a fresh copy when the original feels loose.
- If your ignition is getting sticky, repair before it seizes. Repair is $195-$295; replacement after seizure is $345-$545.
- Never use oil-based lubricant (WD-40) in an ignition - it gums up the pin tumblers.
- Keep ignition keys on a light keychain - heavy keychains accelerate cylinder wear over time.

Ignition repair FAQs
Common questions about car ignition repair.
How much does ignition repair cost?
Cylinder rebuild (if possible): $195-$295. Cylinder replacement with new key: $245-$445 for mainstream brands. European luxury (BMW, Mercedes, Audi): $395-$695.
Broken key extraction plus repair: $285-$545. All include new key cutting and programming.
Can you fix my car's ignition without a tow?
Yes, for most cases. Mobile ignition repair works for all common brands and models. We come to your car, diagnose the issue, and repair or replace onsite.
Only rare cases (complete cylinder destruction, integrated module failures) may require dealer service.
Why won't my ignition turn?
Common causes: worn cylinder pin tumblers (most common), corroded internal parts, bent or seized lock mechanism, broken key fragment stuck inside, damaged BCM/ignition electronic connection. We diagnose onsite to identify the specific cause.
Can you replace the ignition cylinder?
Yes. For most makes and models, cylinder replacement is a standard mobile service. We install a matching new cylinder, cut keys to fit, and program the transponder chip.
Typical replacement: 60-90 minutes onsite.
My key is stuck in the ignition - can you help?
Yes. Broken key extraction plus cylinder assessment is a common service. We extract the broken piece, evaluate cylinder condition, and either rebuild or replace as needed.
Total job 60-120 minutes.
Do you work on European car ignitions?
Yes but with caveats. European luxury cars (BMW, Mercedes, Audi, VW) often have integrated ignition/immobilizer modules that are more complex than domestic or Asian brands. Repair is possible but takes longer and sometimes requires bench work.
Typical European job: 90-180 minutes.
Can you program a new key after cylinder replacement?
Yes. Transponder programming is included in the cylinder replacement service. After installing the new cylinder, we cut a matching key blade and program the chip to match your vehicle's immobilizer.
Works for Ford PATS, Honda HISS, Toyota H-chip, Chevy PassKey, and all other major immobilizers.
What if my ignition is old but still works?
Proactive repair is cheaper than emergency repair. If your ignition is getting sticky or hard to turn, we can rebuild the cylinder with fresh pin tumblers for $195-$295. Waiting until it seizes means full replacement at $245-$445.
Proactive service saves money and avoids emergency lockouts.
Can you match my existing key to a new cylinder?
Yes. For most cars, we can cut the new cylinder's key to match your existing key pattern so your old key continues to work. This is convenient if you have multiple keys in circulation or if you want to keep using your current house/work keyring.
Do you fix work truck ignitions for fleets?
Yes. Commercial and fleet vehicle ignition repair is in scope. We handle Ford F-150, Chevy Silverado, Ram 1500, Nissan Titan, and other work trucks.
For fleet customers we offer bulk pricing and priority scheduling to minimize downtime.
Will cylinder replacement affect my car's warranty?
Locksmith cylinder replacement typically doesn't affect warranty status. We use OEM-compatible cylinders and proper installation procedures. The car manufacturer warranty remains intact for all other systems.
Some manufacturers may note the repair on service records, which is informational only.
Can you work on my ignition at my office parking lot?
Yes. Mobile ignition repair is our standard service. We come to your car wherever it's parked - home driveway, office parking lot, shopping center, roadside.
We need access to the driver's side to reach the ignition cylinder.
