How Much Is a Car Ignition Replacement?

In the U.S. as of 2025, expect to pay about $120–$450 to replace an ignition switch, $150–$500 for an ignition lock cylinder, $350–$900 for a complete ignition assembly, and $400–$1,200+ for push‑to‑start/electronic modules; taxes, programming, and towing may add more. Prices vary by vehicle make, security features, labor rates, and whether you use a dealership, independent shop, or locksmith.

What “ignition replacement” can mean

“Ignition replacement” can refer to different parts of the starting system. Costs depend on which component fails and how complex your car’s anti-theft system is.

The list below explains the main components involved in ignition service and their typical price ranges, including parts and labor.

• Ignition lock cylinder (where a physical key turns): Parts $75–$250; labor 1.0–2.5 hours; typical total $150–$500. Rekeying to match your existing key can add $30–$90; transponder key programming can add $75–$180.
• Ignition switch (electrical portion behind the lock): Parts $30–$200; labor 0.7–2.0 hours; typical total $120–$450.
• Complete ignition assembly (housing + lock cylinder + switch): Parts $200–$600; labor 2–4 hours; typical total $350–$900.
• Push-button/start systems and electronic steering lock modules: Often require programming/initialization; typical total $400–$1,200+, higher on luxury brands.

These ranges reflect common U.S. labor rates ($95–$180/hour) and widely available parts. Premium brands, sophisticated anti-theft systems, and limited parts availability can push costs to the upper end.

Cost factors that drive the price

Several variables determine where your quote lands within or outside the typical ranges.

• Vehicle make/model and security features: Transponder keys, smart keys, immobilizers, and electronic steering locks increase parts and programming time.
• Labor rate and book time: Shops bill by regional rates and manufacturer labor guides; steering-column disassembly can add hours.
• Key programming and rekeying: Matching the new cylinder to your existing key and programming transponders/fobs adds fees.
• Where you go: Dealerships tend to charge more; independent shops and mobile locksmiths can be cheaper and faster for lock-cylinder issues.
• Towing or mobile service: Local tow runs $80–$200; some locksmiths waive a modest service-call fee with repair.
• Parts choice: OEM parts generally cost more than quality aftermarket; used/reman can save, but verify compatibility and warranty.
• Availability and complexity: Backordered parts or modules requiring factory coding can delay repairs and raise costs.

Understanding these drivers helps you compare quotes on an apples-to-apples basis and avoid surprises from programming or towing add-ons.

Typical price examples (U.S., 2025)

Real-world ranges vary by region and vehicle condition, but the examples below illustrate what owners commonly pay for parts plus labor.

• 2008–2016 Toyota Corolla: Lock cylinder $220–$420; ignition switch $150–$300; complete assembly $350–$650.
• 2006–2014 Ford F-150 (keyed): Lock cylinder $250–$500; ignition switch $180–$380; complete assembly $400–$750.
• 2012–2018 Honda Civic: Lock cylinder $230–$450; ignition switch $150–$320; complete assembly $380–$700.
• 2015–2021 Subaru Outback (keyed trims): Lock cylinder $260–$500; ignition switch $170–$350.
• 2014–2019 Mercedes-Benz C-Class (push-to-start/ESL): Electronic steering lock or start module $700–$1,200+ with programming.
• 2015–2022 BMW 3 Series (push-to-start): CAS/FEM-related start module or steering lock service typically $650–$1,100+ with coding.

Luxury models with integrated electronic locks and coding requirements skew higher; common mainstream vehicles often fall in the midrange.

How long the job takes

Time on the rack or at your curb usually runs 30 minutes to 3 hours. Ignition switches can be under an hour on some cars; lock cylinders often take 1–2.5 hours. Complete assemblies or push-to-start modules may require 2–4 hours including programming. Mobile locksmiths often complete cylinder jobs same-day.

DIY versus professional

Some ignition repairs can be done at home, but modern security systems make professional service the safer bet for many vehicles.

Use the points below to decide whether DIY makes sense for your situation.

• Older keyed vehicles without immobilizers: DIY is feasible with basic tools; parts $30–$120. Disconnect the battery and mind airbag wiring in the column.
• Vehicles with transponders/smart keys: DIY often requires scan tools and security codes; a misstep can immobilize the car. Professional service recommended.
• Rekeying considerations: Replacing a cylinder without rekeying means one key for the doors and another for the ignition; rekeying solves this for a small added cost.

If you’re not equipped to program keys or deal with steering-column airbags, a locksmith or shop can save time and reduce risk.

Warranties, recalls, and insurance

Before paying out of pocket, check for coverage. Some extended warranties include ignition components. Certain models (for example, the GM ignition switch recalls from the 2000s–2010s) were repaired at no cost—use your VIN to check open recalls at NHTSA.gov/recalls. Comprehensive insurance may cover vandalism-related ignition damage, and roadside plans (AAA, some credit cards) can offset towing or locksmith fees.

How to get a solid quote

Clear information helps shops price the job accurately and avoid hidden fees.

Follow the steps below when calling a dealership, independent shop, or locksmith.

1. Provide your VIN and a description of symptoms (key won’t turn, no crank, intermittent power, etc.).
2. Ask for a written parts-and-labor breakdown, including programming, rekeying, taxes, and any shop or mobile fees.
3. Confirm parts type (OEM vs aftermarket) and availability; ask about lead times.
4. Verify whether key/fob programming and immobilizer relearns are included.
5. Ask about towing or mobile service options and charges.
6. Get the warranty terms on parts and labor (12/12 is common; some offer longer).

A detailed quote lets you compare options fairly and prevents last-minute add-ons for programming or keys.

Ways to save

You can trim costs without sacrificing reliability by making a few smart choices.

• Get a mobile locksmith quote, especially for lock-cylinder issues—they can be faster and often cheaper than dealers.
• Compare at least two estimates from a dealer and an independent shop.
• Select quality aftermarket parts with a solid warranty when OEM premiums are high.
• Have the new cylinder keyed to your existing key to avoid rekeying doors or carrying two keys.
• Leverage AAA or employer/member discounts and ask about coupons or off-peak scheduling.

These steps often shave $50–$200 from the final bill and reduce downtime.

Bottom line

For most cars, ignition replacement runs $120–$500 for a single component and $350–$900 for a full assembly, with push-to-start systems from $400 to over $1,200. Your exact price depends on the part that failed, your vehicle’s security system, labor rates, and where you have the work done. Gather a detailed quote with programming and towing included, and consider a locksmith for cylinder-related fixes.

Summary

Ignition replacement costs vary widely: $120–$450 for switches, $150–$500 for lock cylinders, $350–$900 for full assemblies, and $400–$1,200+ for push-to-start modules. Factors include vehicle security features, labor time, and service provider. Check for recalls and warranties, compare quotes, and consider locksmiths to save money without compromising quality.
