Where to get a replacement key and what it costs

You have three main places to get a car key replaced: the car dealership, a locksmith, or a big-box retailer that cuts keys. The dealership is usually the most expensive option but guarantees the key will work with your specific car model. A locksmith or retailer is faster and cheaper for older cars, but may not be able to program newer keys that have electronic chips inside.

Cost depends on what kind of key you need. A basic metal key costs $10 to $30 at a retailer or locksmith. A key fob (the remote that locks and unlocks your car) costs $50 to $200 at a locksmith and $200 to $500 at a dealership. Newer cars with push-button start systems or keyless entry may require a dealership visit, which can run $300 to $1,000 for the key and programming combined.

The dealership needs your Vehicle Identification Number (VIN), which you can find on your registration, insurance card, or the driver's side dashboard. A locksmith or retailer needs to see your car in person or have you describe the key type. If you have a spare key at home, bring it along — it speeds up the process and sometimes lowers the cost.

Key Takeaways

  • Locksmiths and big-box retailers are faster and cheaper than dealerships for basic metal keys, but dealerships are necessary for newer cars with electronic key systems.
  • A straightforward metal key costs $10 to $30, while a key fob ranges from $50 to $500 depending on where you go and what your car requires.
  • You will need your Vehicle Identification Number (VIN) for a dealership or a physical description of your key for a locksmith or retailer.
  • Newer cars with push-button start or keyless entry almost always require a dealership visit and can cost $300 to $1,000 total.

When to go to a locksmith instead of the dealership

A locksmith is your fastest and cheapest option if your car was made before 2000 or has a straightforward metal key with no electronic components. Locksmiths can cut and code these keys on the spot, often while you wait. Many locksmiths come to your location, which saves you a trip if your car is disabled or you are stranded.

Locksmiths also work well if you need a spare key quickly and do not want to wait for a dealership appointment. Some dealerships have long wait times, especially in busy areas. A locksmith typically charges $50 to $150 for a basic key, compared to $200 or more at a dealership for the same key.

The downside is that not all locksmiths can program newer key fobs or transponder keys (keys with computer chips). Before you call, tell the locksmith your car's year, make, and model so they can tell you whether they can help. If they cannot, they will direct you to a dealership or a locksmith who specializes in your car brand.

What you need to know about dealership replacement keys

A dealership is the only place that can replace a key for most cars made after 2010, especially if your car has a key fob, push-button start, or keyless entry. The dealership has access to your car's security codes and can program a new key to match your vehicle's computer system. This is why dealership keys cost more — you are paying for the programming and the may provide that the key will work.

To order a replacement key from a dealership, call the service department and give them your VIN. They will look up your car's key type and tell you the cost and how long it will take. Most dealerships can have a key ready in one to three business days, though some can do it faster if you come in person. You will need to show a photo ID and proof of ownership (your registration or title).

Some dealerships charge extra for programming if you bring in a key cut elsewhere. If you already have a spare key at home, bring it with you — the dealership can use it to speed up the process and may charge less. If your car is still under warranty, check whether key replacement is covered before you pay.

How to replace a key fob or remote

A key fob is the handheld remote that locks and unlocks your car from a distance. If your fob is broken or lost, you have two options: replace just the fob shell (if the electronics still work), or replace the entire fob with new electronics.

If only the plastic shell is cracked or worn, you can buy a replacement shell online for $10 to $30 and move the electronics from your old fob into the new one. This works only if the buttons and circuit board inside are still functioning. You can find replacement shells by searching for your car's year, make, and model on Amazon or eBay.

If the electronics are broken, you need a new fob. A locksmith can program an aftermarket fob for $50 to $150. A dealership fob costs $200 to $500 and includes programming. Aftermarket fobs work on most cars, but some newer vehicles require a dealership fob. Ask the locksmith or retailer whether their fob will work with your car before you buy.

Steps to take if your key is lost or stolen

If your key is lost or stolen, your first step is to decide whether to rekey your car's locks. Rekeying means changing the lock cylinders so your old key no longer works. This is important if your key was stolen or if you lost it in a public place and cannot find it. Rekeying costs $150 to $300 at a locksmith and $300 to $500 at a dealership.

You do not have to rekey if your key was lost in a private place (your home, your office) and you are confident no one else has it. In that case, you can straightforward get a replacement key made. However, if there is any chance someone else found it, rekeying is worth the cost for peace of mind.

Contact your insurance company to ask whether key replacement or rekeying is covered under your policy. Some comprehensive or roadside information plans cover part of the cost. If your car is financed or leased, contact the lender or leasing company — they may require you to rekey if the key was stolen.

What to do if you are locked out of your car

If you are locked out and need to get into your car right away, call a locksmith or roadside information service. A locksmith can unlock your car in 15 to 30 minutes and costs $50 to $150. If you have roadside information through your insurance, auto club, or car manufacturer, call them first — they often cover lockout calls at no extra charge.

Do not try to break into your own car. Forcing a window or door can damage the vehicle and cost more to repair than paying a locksmith. A locksmith has the right tools and will not damage your car.

Once you are back in your car, get a replacement key made as soon as you can. If you do not have a spare, keep one in a safe place at home so you are not locked out again. Some people keep a spare key in a magnetic box under the car, though this is less find than keeping it inside your home or office.

Aftermarket keys versus original manufacturer keys

An aftermarket key is made by a third party, not by your car's manufacturer. Aftermarket keys are cheaper — usually $20 to $100 — and work on most cars. An original manufacturer key is made by your car's brand and costs more but is may provide to work and may last longer.

For older cars with straightforward metal keys, aftermarket and original keys perform the same. For newer cars with electronic components, aftermarket keys may not work as well or may not work at all. Some newer cars require a dealership key because the security system is proprietary.

Before you buy an aftermarket key, ask the seller whether it is compatible with your car's year, make, and model. A locksmith can tell you whether an aftermarket key will work for your vehicle. If you are unsure, an original manufacturer key from the dealership is the safest choice, even though it costs more.

Frequently Asked Questions
