Check the Batteries Before Replacing Your Key
If your Mercedes key isn’t working, it’s essential to determine if the issue lies with the key or the batteries. If your key fob fails to lock/unlock the doors, or if it won’t start the vehicle in models with KEYLESS-START® or KEYLESS GO®, the batteries might be the culprit.
Replacing Batteries in Older Mercedes SmartKeys
For older models with a traditional ignition key:
- Locate the key blade release switch and slide it.
- Remove the key blade.
- Flip the key over and find the slot at the top.
- Insert the key blade into the slot to release the back cover.
- Remove and replace the battery. A gentle tap on a hard surface may help dislodge the old battery.
Replacing Batteries in Newer Chrome SmartKeys
For newer models with push-button start:
- Press the button on the back of the key fob.
- Slide off the plastic cover.
- Pull out the battery tray.
- Replace the battery (most newer models use CR-2032 batteries).
What to Do If You Need New Mercedes-Benz Keys
If changing the batteries doesn’t resolve the issue or if your keys are lost or stolen, you’ll need to get new Mercedes-Benz keys that must be programmed to your vehicle.
Can I Replace My Mercedes-Benz Keys Myself?
Unfortunately, no. The complexity of modern onboard computers in newer Mercedes models makes DIY replacements impractical.
