4 important things to know about car keys

Car keys are an integral part of your vehicle and there are several different types of keys depending on the make and model of your vehicle. Car keys will allow you to get into your car, start it, and lock the car when you're done using it.

transponder key

Most cars made after 1995 have a transponder chip built into the key. Once the key is inserted into the ignition, the engine control unit (ECU) will send a message to the key and allow the car to start if it receives the correct message in response. If the ECU does not receive the correct message, the vehicle will not start.

key replacement cost

Losing your keys is difficult and can be costly, depending on the type of car you own. If you lost your key along with your key fob, replacement costs can start at $200. This must be done at the dealership as the key replacement requires special equipment. For a Lexus vehicle, a new key fob that includes programming costs $374, while a BMW key replacement can cost up to $500.

Key lock in trunk

Locking your keys in the trunk can be frustrating, but it happens more often than you might think. With a single movement of the hand, the keys fall when you unload the products. To solve this problem, the dealer can make an inexpensive key that will open the doors but not start the engine. Thus, you can open the trunk and get the original set of keys. Be sure to bring your ID and proof of ownership of the car to the dealership to expedite the process.

Key replacement

There are several ways to replace your car keys. The first is to visit a local car mechanic, as they have sophisticated equipment. Searching the Internet for an aftermarket car smart key may provide you with another key replacement option. The third option is to get a set of keys from the dealer. The last option is the fastest and most reliable.
