Thank you so much!! My manual does not make it clear that I had to hold the lock button down while I was pressing the unlock 5 times so the reset didn't work before. This has saved me buying a new fob.

[@iofix]

Glad it helped :)

OMG you are a star you have saved me a fortune plus all the hassle of not being able to lock my van all over Christmas. Your trick also works on Mercedes VIto Vans!! There are probably hundreds of Vito drivers that will have the same problem if they change their van battery. It might be worth adding the words VITO too to your title. Then other vito drivers would be so pleased. Thank you so much for posting this.!! Happy Christmas!

Great, glad it helped, and thanks for the suggestion.

OMG thank you I thought my key was dead after it got stuck in the cylinder and wouldn’t come out and then I searched MBZ on how to keep the wheel straight or turn it all the way to the left to get it out and then I sprayed some liquid graphite in the cylinder and in the door keyhole and the key came out. I changed the battery and then the key fob didn’t work until I saw your video. I thought I was going to have to go to the dealer to spend $400. This is good info …it works.!! 👏

Ok, when you buy a remote control with a new key, how do you operate it on the car, because I bought a key with a new remote, but when I applied this method, it did not work.

[@timpachos3110]

Thank you so very much for this video. I have been without my fob for a few months, as when I changed the car battery, the key fob quit working. I tried new batteries and a couple different things to make it work with no luck. I watched your video and this morning went out and did exactly what you said to do and first time baby. IT WORKED!!! you made my day...

[@iofix]

Glad it helped u - I do my best to try to make videos that will help people.

[@adisbulic8188]

I have tried this method +50 times. I followed the instructions, but after this whole procedure, the lock button only works once, and the key resets again. (both keys)
The problem start when I replaced the battery on both keys two years ago. I tried other more expensive brands of batteries but its still the same. And since then I only use the service key so that these two would not be damaged by unlocking and locking the vehicle manually

[@iofix]

U've obviously got some other issue there but I don't know what I'm afraid.

[@spamerr1995]

Hey bro did you figure out the problem? I’m got same story with my fob, procedure done, but then it resets again (
