HOW TO Mercedes Benz KeyFob Battery Replacement. Smart key keyless BRC c230 sl500 e320 ml320 DIY Fix

This video explains how to replace your battery in a Mercedes Benz Key Fob with built in transponder. The procedure requires two (2) new CR2025 3V button cell batteries (Yes Mercedes requires two batteries, because they just have to one up the competition ;) ). By using two batteries it means that replacement is not required as often. The procedure is VERY straightforward and simple to understand, so don't be intimidated by it, even if you don't work on cars. Once you have your batteries purchased, follow these simple steps: Step 1: Remove your emergency key (silver metal potion on top) by pressing the tab on top of the key. Step 2: Use the short blunt end of the emergency key to press in the tab found in the opening where the emergency key was removed. Step 3: Using your fingernails, remove the top portion of the key by sliding it upwards. Step 4: locate the batteries on the portion of the key you just pulled out and slide them out through the slotted opening on the positive (+) side. Step 4: slide in your two new batteries making sure to keep the positive and negative sides properly positioned (look for the imprinting on the battery holder portion of the key that marks the positive side up, in case you get confused). Step 5: Slide the battery holder back into the key housing and place back in your emergency key. Congratulations, you should now have a working key FOB or Keyless Entry for your Mercedes Benz Vehicle!! The way you initially tell if your batteries need replacing is if your Keyless/Key FOB stops locking/unlocking your door locks (even if your locking system is broken (ie Sclass pneumatic locks are disabled from an air leak or pump failure) you can still see if the FOB is functioning by checking to see if it arms your alarm or causes your lights to flash when the lock or unlock button is pressed.

As seniors, we are often targets for overcharging. My 2005 E320 key fob battery died. I called the local auto mechanic, and they said that it took 30 minutes to change the battery, and it would cost $56 plus tax. That didn't sound right to me, so I started looking on the internet. I found your video, which so clearly explained how to change the batteries. I found the button lithium batteries at Walgreens for $7.50. I got $5 off for my rewards points, so they cost me $2.50 total. It took me about 3 minutes to change them. THANK YOU VERY MUCH! You saved me at least $54.00!

This video is more than seven years old and it is still helping people. It is exactly what I needed. Thank you!

[@seymourfrosty63]

Was told by 3 different dealers/key repair people that i will need to replace the whole fob for £200. This just saved me a bundle.

Lost all keys. Need to fix the 2014 cls 550. Key fob battery. I opened it. Most complicated thing I’ve ever seen.

[@lumpiasauce8699]

I did this but realized the energizer batteries are slightly fatter than the Duracell ones....

[@CurryEnterprises]

I did the battery change but it still will not unlock or lock my doors. It will start the car. What can it be?

[@TheLarryBrown]

Worked great for me, In addition to the key shown in this video, a key which worked exactly as shown in the video, I have another. different, key to the same car. It works differently than shown but I was still able to use your insight to get into it. On that one the metal valet key has a tiny prong on the front of it that is like a flat screwdriver. I was able to insert that into the body cavity and press a tab and release the battery tray. The other side of the tray had a static lip that held that side in, but once the one side was released that static lip got enough clearance that it could would release.
