Car Key Types


types of car keys

The technology behind cars has developed at a tremendous rate. We have better drive tech, more innovative safety features, better materials than ever before. It’s truly a golden age for the cars. One item that seems to be as vulnerable as ever is the car key. Though, many vehicles nowadays rely less on a physical key to open and lock a car or turn on and off the engine, there are still many older makes and models that rely just on one metal key blade to do the minimum necessary to drive the car. Regardless, whether it is a metal key, remote key or flip fob key, we rely on them to open our car doors, to start the engine, and to lock up the car again.


Car keys come in various types


  • Older models are more straightforward, non-remote car keys, which don’t contain any other features other than the strictly mechanical key individually cut for each vehicle.

    manual transponder car key


  • The next upgrade of the car keys is where the regular key has attached to it a car remote.

    remote car key


  • Newer models use remote car keys where the blade folds into it, also called flip fob keys. That remote typically opens, locks, and activates other security features. Having your vehicle equipped with this fob key means that you are still using a metal key to turn on and off the engine.

  •  The newest models use a car key fob, which is more advanced than the previous examples, which does not have a metal blade but still, it must be inserted into the ignition lock to start the engine.

  • And lastly, a key fob that is needed to be present when to lock/unlock and start the engine. With this type of key fob, to start the engine, a push-button ignition must be pressed. This push-button ignition is on the dashboard near the steering wheel. Some makes and models have incorporated into the remote an emergency blade, which can be used to enter the car in any event that the key fob failed.

Common Car Key Issues


As crucial as our car keys are, they remain one of the most fragile components we have. They are vulnerable to myriad causes of damage and breakage. To understand why the fob key is prone to various issues that could render it unusable at times, we must understand what it’s in them. So, here are a few facts about FOB KEYS. For the past 20 years, the car keys have gone through a vast transformation from a simple mechanical key to a more sophisticated keyless entry system. Being that the auto theft is a very lucrative business, expensive car manufacturers like Audi, Volvo, BMW, and Mercedes have invested millions of euros in ensuring that the security of the fob keys is not compromised. The information stored in these fob keys can range from the mileage and last time-driven, fuel level, vehicle identification number to GPS data. This information can be used by insurance companies and law enforcement to prosecute those who attempt insurance fraud and more.


Here are some of the most common issues:


  • Worn blade Wear and tear altering the unique cuts on the key – if the cuts are off by even a little, the key might not turn the ignition switch or door lock, any longer, and will require a replacement key.

  • Key snaps in a frozen lock – a common affliction of the winter morning. As we nudge and twist the key with all our might, it can snap and get stuck in the lock, rendering it useless.


    broken car key blade


  • Key fob dropped repeatedly or from a height– with each drop, you might not think anything of it. Still, many falls, especially onto a hard surface or from any significant height, can cause physical damage, as well as a deficiency in its operation.

  • Damaged circuit board The circuit board is what tells the car what to do once pressing the buttons. The circuit board is an electronic component located inside the plastic case. The circuit board is prone to many issues because of repeat falls, and if this is the issue, we will test the circuit board, and if determined that any of the components on the circuit board are to be at fault, we will proceed to replace. A bad microswitch is the most common fault on the fob key circuit board. It is replaceable, and once it is done, it restores the fob key to its full functionality.

  • Fob accidentally crushed under car wheel or other weight – an unfortunate accident more common than you might think that leaves the car fob key literally in pieces.

  • Broken flip fob blade

  • Broken case or button pad

  • Key blade bent – if you have a habit of keeping keys at the bottom of your bag, or if you hold them in your hand and lean them against surfaces, then over time, it can bend. They’re not as mighty as you might think, even though they are metal.
