HAVE AN EMERGENCY BMW OR MERCEDES KEY OR ELECTRICAL PROBLEM? CALL (972) 693-1868. There are few things more irritating than rushing to get on the road only to find that you are accidentally locked out of your car. This can be extra frustrating for Mercedes owners in Dallas since your vehicle has to be brought into a dealership for a key replacement and it can take days to get your car back. But there's a solution–Advanced Locksmith. We specialize in locksmith services for Mercedes vehicles both old and new. Most Mercedes on the road nowadays are accessed by fob which sends a pre-programmed unique electronic signal to the car, allowing you to access it. This makes it much harder for thieves, but it also makes the process of getting a new key or fixing an issue much longer. We have the knowledge and equipment to create a key replacement for you the same day.


To combat the inconvenience Mercedes owners must go through when working with a dealership, Advanced Locksmith offers a mobile service that will come to you to fix the problem. Our truck has all the necessary equipment to create a key replacement. Have you been wanting a second key made for your vehicle? We will create a second key/fob for 50% of the first replacement.


Our staff is not only trained in locksmithing but also the electrical systems that modern manufacturers use to allow for greater security. We are practiced in dealer level diagnostic procedures so that we can pinpoint the reason a client's auto electrical system is malfunctioning. Because it is useless to replace a key if the problem lies in the car's systems.

As computers go hand in hand with modern cars we can also look at the programming of the CPU in the vehicle. Our technicians can reprogram or clone the various components such as the engine control unit, body control module, transmission, immobilizer and more.


We’re a full-service Mercedes-Benz locksmith company. As such, we have all your key-related needs covered. Our complete range of services includes everything from key duplication to key programming and more.

Mercedes Key Not Detected?

You've just received a new message on your car's display that reads, "Mercedes key not detected." Now what?

There are several reasons this could happen, with the two most common being the battery is growing weak and is in need of replacement, or it has been exposed to water and is malfunctioning.

If water exposure is the culprit, you may need to replace the FOB entirely. However, if dead batteries are the problem, a simple replacement is the answer. It is worth noting that once the battery has been refreshed, you will not need to reprogram the key unless you are replacing the FOB entirely.

Should you make an appointment at the dealership to accomplish this? Sure, you could, but you may have to wait longer and pay significantly more for the services they offer.

Save yourself time, hassle, and money when you partner with our experienced Mercedes auto locksmiths. In most cases, it takes us very little time to complete this service for you. Call our team for more details!

Mercedes Key Battery Type

What Mercedes key battery type will you need if you want to change the batteries in your key FOB? To make things easier for you, Mercedes has made the battery type CR 2025 a standard feature across all key FOBS. The tricky part is knowing how many your key will require. We've made it simple with the following chart:

  • Smart keys need 2 x CR 2025 batteries
  • Chrome keys require 1 x CR 2025 battery

How to Know When You Need a Mercedes Key Battery Change

If you're experiencing issues trying to gain access to or start your car, those are two pretty sure signs you're in need of a Mercedes key battery change. Some of the other telltale signals include:

  • Issues starting your vehicle because FOB sensor strength is weakening
  • Trouble locking and unlocking doors
  • Your key's range seems to be getting shorter, so you must get closer to your vehicle for it to work
  • You see a warning light pop up on your dash, which points to a charging system discrepancy
