Question 1

What is the cheapest way to replace my Mercedes-Benz key?

Accepted Answer

Call a mobile locksmith before you call the dealer. Mercedes owners who go straight to the dealer pay $600 to $1,500 or more for a single key. One C-Class owner was quoted $617 for a spare, and a GLC 43 owner paid $1,100. With EZ Car Keyz, a Remote Head Key for the 2007 Mercedes-Benz SLK is around $$185, and that includes everything. You do not need to tow your vehicle, you do not need to wait weeks for a key to arrive from Germany, and you do not get hit with separate charges for the fob, blade, programming, and diagnostics.

Question 2

How much more does all-keys-lost cost vs a spare?

Accepted Answer

Significantly more, on any Mercedes. When you still have one working key, adding a spare is a simpler programming job. When all keys are lost, the EIS/EZS module needs to be read and reset, old keys need to be deactivated, and new keys need to be written to open slots. Mercedes owners report dealer AKL quotes of $1,000 to $2,000 depending on the model. One owner described a $1,550 dealer bill for a replacement key. The best advice is to get a spare made while you still have a working key. It will save you a thousand dollars or more down the road.

Question 3

Are aftermarket Mercedes-Benz keys cheaper and do they work?

Accepted Answer

Mercedes is one of the trickiest makes for aftermarket keys. On older FBS3 models like the W204 C-Class and W211 E-Class, aftermarket keys and shells can work well when programmed by a locksmith with the right tools. One locksmith noted that aftermarket shells sometimes last even longer than OEM on these cars. But on newer FBS4 models like the W205 C-Class and W213 E-Class, keys must be ordered pre-coded to your VIN and aftermarket blanks will not program. We carry the correct keys for your specific Mercedes-Benz model so you are not gambling on compatibility.

Question 4

How many buttons does the 2007 Mercedes-Benz SLK key have?

Accepted Answer

Your 2007 Mercedes-Benz SLK key has 4 buttons. The button count and key style help identify exactly which fob your vehicle uses, since Mercedes uses different key generations across model years and trim levels. Keyless go models have a different internal chip than basic remote keys on the same platform. When you call us, having this detail helps us confirm the right key before we head out.

Question 5

Are there hidden fees I should watch out for?

Accepted Answer

Not with us. Our price is our price: key, cut, program, mobile service, all in. But Mercedes dealers are known for stacking charges. One AMG GT owner broke down a $1,250 quote as $800 for the key and $300 for programming plus tax. A GLE owner showed an invoice over $600 for the fob with the emergency blade billed separately at $70 to $80. Another owner tried to buy a key from the Mercedes USA website for $250, but the dealer cancelled the sale and insisted on selling their own for $600. With EZ Car Keyz, $$185 is the total. Period.
