Steps to Take When You Lose Your Car Keys

Take a Deep Breath and Search Thoroughly

Start with a deep breath and think back to the last time you had your keys. Check the usual spots—pockets, bags, or your key ring. Sometimes, they hide in unexpected places, like a jacket pocket or under the car seat.

If you’re at home, search around your designated key spot. Car keys often fall off tables or shelves without you noticing.

If you’re still empty-handed, mentally retrace your day. Did you leave your keys at the store? Or maybe on the kitchen counter while juggling groceries? Walking through your recent activities often jogs your memory.

Identify Your Key Type

Before you call for help, it’s important to figure out what type of key you’ve lost. Different keys require different replacement processes:

  • Traditional Car Keys: If you have an older car (pre-1990s), you likely use a traditional car key. These are the simplest to replace, and a local locksmith can usually make you a new key right away.
  • Key Fobs: These are popular in cars from the ’90s onward. Key fobs allow keyless entry, but there’s usually a traditional key tucked inside for ignition. If you’ve only lost the fob, you can buy a key fob online or at the dealership and program it yourself.
  • Switchblade Keys: These combine a key fob with a fold-out key. Losing one of these requires a trip to the dealership unless you just need the traditional key portion replaced by a locksmith.
  • Transponder Keys: These offer added security by communicating wirelessly with your car. If lost, you’ll need to visit the dealership to get a replacement car key, and towing might be necessary.
  • Smart Keys: The most advanced of the bunch, smart keys allow keyless entry and ignition. They also rely on proximity sensors. If you lose one, replacing a car key of this type will definitely require dealership assistance.

Contact a Locksmith or Roadside Assistance

Once you’ve identified your key type, you’ll need to decide whether to call an automotive locksmith or rely on roadside assistance.

For a traditional car key, your best bet is a local locksmith. They can quickly make a new key on-site, usually for a reasonable price. Locksmiths also cover older cars that use simpler keys, so if you drive an older car, this is the fastest option.

However, if you’ve lost more advanced keys like a transponder or smart key, you’ll need roadside assistance to tow your car to the dealership. Be sure to have these details on hand when you call:

  • Vehicle identification number (VIN)
  • Car’s make, model, and year
  • Proof of ownership (car insurance or registration)

This helps speed up the process and ensures you can get your car back as quickly as possible.

Replacing Car Keys: Types and Costs

Let’s talk about money. How much does it cost to replace your car key? It depends on the type of key and where you get it replaced:

  • Traditional Keys: These cost as little as $10 if you go to a hardware store, or slightly more if a locksmith comes to you.
  • Key Fobs: Expect to pay around $50–$100, depending on the model. If you’re comfortable programming the key fob yourself, you can save some money.
  • Switchblade Keys: These start at $300, and you’ll likely need towing to the dealership for a full replacement.
  • Transponder Keys: These can run you $200 or more, plus towing if your car is immobilized.
  • Smart Keys: These advanced keys range from $200–$500, plus any towing fees.

Helpful tip: If you have a spare key, always keep it in a safe spot. It’ll save you the trouble (and cost) of calling a locksmith or dealership. And don’t forget to check if your car insurance or AAA membership offers roadside assistance to cover any towing fees.

Tips Prevent Losing Your Keys Again

No one wants to go through this again, so here are some helpful tips to avoid losing your car keys in the future:

  • Check your pockets

Get into the habit of emptying your pockets when you get home to avoid your keys ending up in the laundry or under the couch.

  • Use a Bluetooth tracker

Attach a Bluetooth tracker to your key ring. You can use your smartphone to find them if they get lost.

Create habits that reduce the chances of losing your car keys again—like checking before leaving any location.
