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
Michael

You can only get a key and get it programmed from Mercedes. End of story

Without wishing to be Job's comforter there is an upside.
Unless your house is burgled and you've left your keys in plain sight your SLK is very difficult to steal :wink:

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.)

YES IT CAN BE DONE... and I have done it!!. There was a guy from Texas (on ebay) that advertised to program the new key for $120. I found out we speak the same language, so I dealed with him directly over the phone. I sent him my old broken (not working at all) black key, and a few days later, he sent back a brand new chrome style key fob for total of $100. The new key is working perfect since. I recently tried to find his ad on ebay (for future use), but couldn't find it anymore...


Btw, he didn't cut the metal key, but provided a new uncut one. I found a local lock smith that cut it for $30.... so new fully functional keyfob for $130.... forget the stealers..

Perhaps he was an MB employee lining his pockets>:D

You cannot find him now maybe because he is doing 10-15 years for car theft :D :D :D

Ok so from the R171 model onwards, you cannot do the re-programming anymore ( ie where one presses a combination and sequence of buttons in the car ignition to reprogram the fob for your car)?

I bought new key from dealer in Portland Oregon for $230 USD. Why bother with Stealers or other dishonest people.
$500 USD in HK sounds like too much you should try another dealer. I hope you find it for a better price.

They don't actually reprogram a blank key from what I can gather, they float off one of the chips from the old key and solder it onto the new one... still clever stuff though.

I'd stick with a dealer on this one...

I don't exactly know how the keyfob works, but my old key was broken and completely not working (tried to fix it myself by cleaning, resoldering some of the joints on the circuit board). When he returned the old key and the new keyfob ... the old keyfob's circuit still intact: no chip, IC missing (I still sometime played with the broken key, trying to fix it, just for fun)

I just went through this as I needed a backup key for a recently purchased 05 350. I was quoted between $266 & $310 from four Raleigh area dealers. In the US mobile locksmiths legally have the equipment to cut smart keys. The first guy I called wanted $275, a local locksmith referred me to a mobile locksmith who is doing the job for $170. (Ouch!)

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.
