Replacement for Mercedes-Benz IYZ3312 Keyless Entry Remote Car Key Fob Control ,FCCID:IYZ3312,by AUTOKEYMAX (Pair)

I tried programming myself. I tried calling 5-6 locksmiths all but one said only the dealer could do it. One said he would do it for $500. Then I called a mechanic who works on old Mercedes, he knew of a guy that could do it. He was busy but within a few days he stopped by and programmed it and cut the blade for $150 plus tax - took almost an hour with a custom MB only laptop plugged into the car. He had to pay a fee to MB for the necessary codes.Dealer prices were $69 for blade key and cutting. $192 for key fob (no blade key) and $169 to program. Those are at Grapevine Texas MB dealer in DFW area. So cost of using this Amazon key and finally getting it programmed was just under half the dealer cost. Still expensive, but much better. The locksmith confirmed the components of the key are made by same manufacturer as the dealer keys, but symbol is covered.May want to confirm you have a locksmith in your area that can do it before you buy this key.The DFW Texas area locksmith was Al at 561-215-6048

Zero stars. Locksmith will not program for less than $275 plus additional $65 to cut key. Will not work for proximity locking or other functions. Buttons only. Stay away. Company does not respond. Mercedes is not listed as a company on the website for self programming. Dealership is $350 to $400 out the door.

All four buttons work after programming. Even though the original key had only two buttons + panic. This key has three buttons + panic. I programmed it with VVDI MB Tool. I did not rate durability in this review because I only just made the key. So far it works as it should. I just purchased two more keys for my next clients who may need a Mercedes Benz key programmed.

Cost is to high, but they have you by the balls

I had to return the key because no one would program it to the car. Only the dealer will program them and they will only program a key that you have purchased from them, the dealer.

Came with dead battery 🔋

Was a good product but did not work with the push button feature on the car

I couldn’t find a locksmith who could program the key except one. He wasn’t viable because h wanted $750 to program a $30 key I got on AMAZON. I thought the $30 dollar AMAZON price was good until I found out that I couldn’t get it programmed in my area for a rational price. Before you buy one from AMAZON be sure it can be programmed at a reasonable price. I finally priced the key at the Mercedes dealer. I paid $30 plus for the AMAZON KEY and at least $150 for programming with little guarantee. The dealer wanted $350 which was to close to the total AMAZON total cost. The dealer guaranteed their key. I thought the dealer price was unreasonable but I submitted. I recommend the dealer and avoid the wasted $30+ and the wasted time and effort finding a programmer.
