Thank you so much! I did the repair and the whole thing with new batteries only cost $20.00, compadre to the $200+ to get a whole new key shipped through the dealership from Germany. Of course I’d love to order a couple new keys, but you can’t beat a $20.00 repair on a MB.

It took me twenty five minutes, some bad language and four broken finger nails to replace the Batteries on two key fobs. Thank you for making that easier than it might have been.

Thanks for saving my dad over 800$ at the dealer to replace the whole key! It's insane. They told him they could not fix the plastic and would have to get a new key and reprogram it for his car. Now he hadn't told me about his key being worn out and damaged so when I found out I was furious! I've done this to 4 cars before and saved myself hundreds of dollars but I did not anticipate saving him nearly a grand thanks to you my man!

A big thank you! One of the best key shell change demos on youtube. Found that a thin penknife blade saved using my nails on the first opening and was helpful in jiggling the circuit boad free.

This is the best video on here on how to replace the shell with a new one. Saved me a lot of money. Works great so far.

I have a Mercedes Benz CLK 320 with your help I changed my key fob in less than 5 minutes I'm so grateful thank you so much we appreciate you.

Thank you for this. I just replaced my old Mercedes Benz key fob that was all chewed up looking with a brand new shiney one off ebay using these steps. I actually played this vid while I reproduced your steps on mine. It worked like a charm. My original fob was so old and worn the little white plastic interior holder broke in two. But I Super glued it back together and after it dried it held up fine and everything slid back in just like you said. Everything works perfectly now. Thanks again!

Having a nightmare getting the circuit board out...it's like its locked in. Tried with tweezers and it will not budge. 2004 W211 E320 estate. EDIT: Hold that thought...I cracked it....I used a paper clip with a tiny bend in it to pull it out with...Thank you for the great video. PS I was quoted £480.00 to replace the keys by Mercedes Benz...now done for £11.80...Madness!

Thank you for the video. Just replaced mine. I like to share what I did which it's a bit easier. I used the key to open the transponder a bit so you can clear the locking clips. I used a paper clip and stretched out on side. I bent the tip a tiny bit enough so that it could fit in the plastic opening that lock the chip. Once you open the transponder with the key, it clears the locking clips and with the bent clip side, pull the chip out.

Fantastic. Do most things myself but there is so much risk of causing damage that I needed a guide. 100% success. Thank you very much

[locharrow]

Just had the same problem...key not turning, locked st/wheel and no ignition. Did not believe the "fluff" problem till I opened the key....two little squares of fluff right over the sender units. Cleaned the lot with aftershave (Brut of course) re-assembled the key and bingo!! Worked like Many thanks for the info Siri. Selling the 240 CLK now as just bought a key-less go 350 CLK ..great cars.

Very well done with clear and concise instructions. Changed the CR2025 battery on my son's 2003 Mercedes-Benz C240. Subscribed. Keep up the good work.
