Locked Out

This term refers to any scenario in which you are locked out of your car. This happens most frequently when you forget that your keys are in the car and lock the doors. However, you can also get locked out if your car is locked and you lose your car keys.


If your keys are lost or have been stolen, getting a new set of keys made will only solve one problem: Getting you entry to your car again. However, you’ll still have the problem of someone else out there potentially have the keys to your car.

Re-keying is a process by which a lock is changed so that a different key can open it. Instead of replacing the whole lock, you just hire a locksmith to create a new key and then alter the lock to suit it. This is especially useful in the case of lost or stolen car keys since replacing an ignition can be a costly procedure. You can save money and protect your car by re-keying the ignition instead.

Microchip Keys

Technology has made even simple things like keys more secure. Microchip keys contain a programmed circuit inside that transmits a signal to the engine control unit that allows the car to start and disarms its immobilizer. Without that signal, the car won’t start.

If you lose a microchip key, you can’t get a new copy cut the way you would just any old key. You need to see a locksmith who has the equipment and the experience to create a key with the right cuts and a new chip. Because these keys require special equipment and technology, they are more expensive to reproduce.

Keyless Entry

When you are loaded up with groceries or other bags, you don’t want to have to fumble with your car keys to unlock your car while also trying to balance your haul. A keyless entry key allows you to hit a button that unlocks your car doors when you are within a certain range. Usually, one click of the button will open just the driver’s side door, while two clicks of the button will open all the doors. Some keyless entry units also include a button for opening the trunk from afar.

Keyless entry is a common feature on many cars now. If you lose this fob, you won’t be locked out of your car, but you may be inconvenienced.

Because keyless entry requires programming that is unique to your car, it can be expensive to replace this unit. However, doing so will make things a bit easier for you, and having the keyless entry unit will add to the resale value of your car.

Keyless Ignition

Keyless ignition is growing in popularity for new cars. With a keyless ignition, you get a fob that is programmed to send a signal to your car when it is in range. In the place where you would usually insert your key, there is a button that you hit to start the car.
