Heart HorseSmart Remote Control Key Replacements for Mer-ce-des B-e-n-z A B C E G S CLK SLK ML Class, 3 Buttons Remote Car Key Fob Case with 433MHz BGA Chip, W210 Remote Key Case/W169 Remote Key

I've used a lot of these keys because I can get them the next day. They have all so far been good quality and no issues programming them in. The one downside is every key has needed a new battery when I get them. I always keep a pack of quality CR2032 in stock thankfully

I needed to replace the back of my key fob as it had been removed when parked at Meet and Greet.Although it was supposed to be an exact match the replacement back didn't fit so a waste of money

Used for W211 2008, which has three-button, two-batteries key fob. Was difficult to find.Looks great, easy to swap, quality is ok-ish (good for £10 - when it breaks, just get a new one for another £10

The media could not be loaded. I'm extremely satisfied with this product. The key shell is of high quality and fits perfectly. The included BGA chip and NEC blade were easy to install, and the remote control key cover case looks and feels durable. It's a cost-effective solution for anyone looking to replace or upgrade their Mercedes key. I highly recommend it for its quality and compatibility with various Mercedes-Benz models.can’t tell the difference next to a real on but the small key that’s inside is a bit light weight

Had a 2015 merc sprinter in for 2 keys ended using all 4 we had in stock for only 1 to start the vehicle and non operate the remote functions the others are unreadable after trying. Also same experience with a 2011 b-class. Will not be ordering again
