Hi
Good day (lei Ho)

From our local key fob maker, I gather, it will cost about USD 200.00
But the car must be driven to their place to do the programming.

I don't think there is any other way cheaper.
Merc distributorship in our country will cost about USD400.00

So, after knowing the cost of replacement, I keep my spare fob inside my safe box, LOL.

Thank you & have a nice day.

ps: I was also told by our local workshops that the fob duplicated by the key maker, sometime do not work well (once in a blue moon, LOL.)

I lost a key for my 2005 Merc SLK 350 and need to purchase a new one.

However the dealers in HK charge about equivalent to USD $500+ for a new Key Fob.

I saw that some can be self programmed without the need to pay a dealer and if I read correctly 2nd hand key fobs can be reprogrammed?


Can anyone recommend if I can purchase cheaper Key Fobs (may be in the US or UK via air delivery). If anyone can help advise it would be much appreciated.



Many Thanks

Welcome to the forum Michael. I am new here myself and also moved to HK from London recently. For your information, to clone a Mercedes Key, the ignition lock is required in order to decode the hash code required to code up the ignition key. I have looked into getting such a kit (Google Simon Touch), but the kit costs over several thousand Euros, so only viable for someone doing this professionally. The cheaper Chinese kit requires a chip to be removed from the ignition lock module in order to decode the hash code off the memory chip. I believe some guys back in the UK in Milton Keynes are using the cheap Chinese kit as they require the ignition module to be removed from the car.

I understand that there is a guy in San Tung Street in Mong Kok who can do this. I wouldn't purchase a used key from the UK/USA as there are two different type of keys used by MB - one can be erased electronically, but the other requires the memory chip to be removed by de-soldering and then erased in an eprom programmer - not for the faint hearted!

Personally I would get the car off the official dealership - once the hash code is read off the ignition module, they can programme upto 10 different keys!

Good luck.
