  1. Call a locksmith in the area to come make you a new key, or call roadside assistance for a tow. Have your VIN, make, model, and car registration handy so you can prove that you’re the owner of the vehicle. [1]
    • If you have a traditional key, call a locksmith. They can make you a new key right then and there, even without the original key present.
    • If you have a key fob, switchblade key, transponder key, or smart key, call roadside assistance . They will tow your car to the dealer where you can purchase a new key.
  2. The process for replacing your car keys differs slightly depending on what type you have. Think about your car keys and what they look like. There are 5 main types of car keys, including: [2]
    • Traditional car keys: these are common for cars made before the 1990s. Traditional keys are classic car keys without any extra features that you put into the ignition to start the car.
    • Key fobs: these are plastic casings that have buttons on the front to lock and unlock your car (and set off the alarm or open your trunk). Some key fobs have physical keys hidden inside of them.
    • Switchblade keys: these keys are a version of key fobs, but they always have a key tucked inside. To start the car, you simply pull the key out of the fob and put it in the ignition, then fold the key back inside when turning the car off.
    • Transponder keys: these keys look similar to traditional keys, but they have a wireless element inside. Your car will check for this wireless element before turning on.
    • Smart keys: these keys have a proximity sensor inside, which unlocks your car whenever you’re near. Smart keys are often paired with push-to-start ignitions.

  3. When you lose your keys, it’s easy to go into panic mode. Take a deep breath, then retrace your steps . Check all of your pockets, your bags, and even your shoes. If you’re not at home, check the area underneath the car or anywhere you spent time recently. [3]
    • If you have a spare car key, now’s the time to find it. Check your junk drawer or your filing cabinet if you can’t remember where you put it.
    • Once you’ve exhausted every option for where your keys might be, move onto the next step to work on replacing your car keys.

  2. Key fobs vary in price depending on what type of car you drive. In general, though, you can expect to pay no less than $50 (and some car keys can cost upwards of $500). [4]
    • Specialty locksmiths, like auto locksmiths, may be able to replace your key fob for cheaper. [5] Call a local auto locksmith and ask them about their services to see if it’s something they offer.
  3. Switchblade keys are similar to key fobs, but they’re slightly more expensive. Most dealerships charge upwards of $300 for a replacement.
  4. Since transponder keys have a wireless component inside, they tend to be pricier to replace. Most dealers will charge around $200 for a new transponder key.

  1. These modern inventions make it easy to find your keys with just the click of a button. Purchase an electronic tracker on a keychain, attach it to your keys, then set up an account on your phone. Anytime you need to find your keys, you can alert the tracker via bluetooth and listen for an alarm. [10] Popular brands include:
  2. It’s much harder to lose your keys if they’re in the exact same spot every time. Make a designated area for your keys, like a hook by the door or a small dish. Then, you’ll know exactly where to look next time you need to leave the house. [11]
  3. Small, one-colored car keys can be easy to miss. Attach a bright lanyard or a fun keychain to your keyring to make them easier to spot. [12]
    • Plus, a bulky keychain or a long lanyard makes it much less likely that you’ll drop your keys or they’ll accidentally slip out of your pocket.
  4. When you buy a car, you usually get 2 sets of keys. Instead of throwing your spare key in a back closet somewhere, give it to a trusted friend or family member. That way, if you ever lose your keys again, you know exactly where your backup is. [13]

    One thing that you shouldn't do is try forcing the door open yourself. You'll probably damage the weather stripping or scratch the paint. Instead, call a roadside assistance company or an automotive locksmith. They have special tools to open your car without causing any damage. It's usually pretty cheap and quick.
