What To Do if You Lose Your Key

Losing car keys is more hectic now than it was in the past. With the digitization of almost everything around us, cars and keys have earned a spot in the fast-changing world. 


The question remains, what do you do if you lose your car keys? Well, there are different ways to handle this because there are different keys and ways to replace them. Having a spare key helped, but now, only a few cars are manufactured with spare keys, mainly due to security reasons.


Some are basic, the simple key we all know, while others require smart chips to communicate with the car.


Our team here at R&T's Lock and Key has devised replacement methods for car models and their keys. Below you will find different keys and how to replace them.


1. The Traditional Key


Replacing the traditional car key is one of the easiest ways to get your spare. The key is the most basic and requires manual replacement, where a locksmith replicates the key and could make more spares in case you lose your keys again. However, care models that have unique keys or are older will require seasons of locksmiths.

2. Key Fobs


A car key fob was manufactured as an add-on to the traditional key. You can use the fob to start your car. Replacing a car key fob is also easy since they have a ready-made market and are programmable.

3. Fobs With Switchblade Keys


The initial fob was just an add-on to the traditional key. However, as time progressed, the fob was manufactured on the keys. Replacing a car that uses this type of key is harder than those that use the car key fobs because its programming is more complex, and these types of keys need a ready market.

4. The Transponder Key


The transponder key is embedded with a chip that communicates with your car. It is uniquely made for your car model, meaning replacing this type of key is extremely hard. As technology advances, so do the crime rate and the need to secure your vehicle.


Once the key is lost, you must manually tow your car to your dealership. 


5. The Smart Key


The smart key is designed for newer car models with a button to turn it on. The smart key communicates with the car through closeness, which permits the car to turn on with a button. Having to replace the smart key is similar to replacing the transponder key, towing the car, ordering a new key, and programming the new key. 


Replacing a smart key is the most expensive and takes the most time.


What To Bring

When replacing your car key, you will need your original copy of the vehicle registration, driver's license, identification card, and passport. If you are unavailable during the replacement, you can authorize someone else to act in your place, provided they have the essentials required.


Due to security reasons, all the documents mentioned are mandatory. Programming the key to your specific car model is a delicate process that requires authorized and experienced personnel to do the job for you.

Are Mercedes Keys Trackable?


Mercedes-Benz keys come with a variety of advanced features, and some of them include a tracking system. Mercedes-Benz uses a technology called Mercedes me, which allows you to track your car in real-time via your smartphone, tablet or computer, you can also see the last parked location, lock and unlock the car, and also set the climate control to your desired temperature. This feature is available on newer Mercedes-Benz models, and can be accessed through the Mercedes me app.

Does Any Mercedes Key Work?


Each Mercedes-Benz key is programmed to work with a specific vehicle, so not any Mercedes key will work with every vehicle. The key is programmed to communicate with the car's computer system and match the car's unique identification number.

If you try to use a key that is not programmed to work with your vehicle, it will not start the car or may cause damage to the car's electronic system.

If you lose your key or need an additional key, it is best to contact a Mercedes-Benz dealer or a qualified locksmith to obtain a new key that is properly programmed to work with your vehicle. They will be able to provide you with an original key that will work with your vehicle, and will be able to program it correctly.

How Much Does a Mercedes Key Replacement Cost?
