Skoda Fabia 2015 keyless problem

[Manta1600]

I had customer with Fabia 2015 keyless with original key 6V0959752E

I generated XH key the key is programmed and work keyless and remote but the original stop work keyless only emergency

after that I tried maybe all possible XH MQB models but no success to have 2 working keys

I tried to program only the original key and keyless and remote again doesnt work

on the dash fault - B128B00 incorrect key programming - remote control

Finally I programmed 1 XH that work remote and keyless and the original one that work emergency

any clue about this

Hi, Disconnect battery terminal for 10min then reconnect then relearn keys!

Hi, Disconnect battery terminal for 10min then reconnect then relearn keys!

I disconected the battery for around 2-3 minutes without success do you think that need 10 minutes

Thanks

I had same problem on 2019 mqb Polo . It was not a keyless system! But had a similar fault and would not learn remote! I was adding a dealer supplied key using dealer tool.

Someone advised me to disconnect battery for at least 10mins and it work straight away!

Hope you get it sorted.

Thanks if the customer come back will try

Other strange thing is that the programmed XH key work keyless and remote but don't have emergency function

When you program the key 1 time you can't reprogram it again - if you want to program again must generate again with VVDI like new key make again dealer key and program to the car

That is strange, have you an oem or aftermarket keyless key to try, Not Xh ?

I have aftermarket for Passat B8 instock but not tried - will try if the customer come back

I think that aftermarket for passat B8 will work because XH key prepared for B8 passat work on this Fabia

also maybe I have instock the same shape keyless aftermarket but must check

I preffer to program XH keys and I use aftermarket keys only for AKL with Autel

Two days ago I add a keyless remote for the Skoda Fabia 2016 , and there was no problem with the xh mqb keyless, I always do the following to avoid malfunctions
-Switch on all the time throughout the programming process
- keyless inside the ring after disassembling the steering wheel cover

You will not restore original key. I had this situation. All tools tested.

What HX soft use for them?

Did you try after that is the emergency start work?

Did you try to write back the original eeprom and program only the origrnal key?

[drugowaz]

Yes tried all possible options. All i mean ALL. ONLY thing i nit tried is rekearn by odis online. All aftermarket tried.
I had cover this loss by making 2 new keys fir ownrr. And third ori key left like service key.
Problem is not in clyster. Its bcm problem. Ass remote function sits in bcm

What keys did you programmed - XH or aftermarket?

I can't do 2 fully working XH keys - always work only one and they don't have emergency start function

I ordered few aftermaket keys and will call the customer to come back

I suspect that all XH keys that is programmed on VAG keyless cars will not work on emegency start only keyless

I will be very surprised to see video on XH key how work without battery on emergency start

[Manta1600]

Today I tried again with aftermarket key

I programmed first the new key and then the original key - all on the new key work fine + emergency on the original key work only the emergency start

after that I programmed first the origrinal key then the new key and now the original is fully working but on the new key only emergency work

Finaly I think that this car original have only 1 keyless key and 1 emergency key and is not possible to be programmed 2 fully working keys - maybe will be possible if someone do online coding with ODIS

also XH keys aren't good for MQB keyless they dont have emergency start also 1 time programmed the key can't be reprogrammed again on the same car and if the customer lost the original key with the XH key will be imposible to be programmed new key must do AKL

Did you try, clear codes and remove battery terminal for 10 minutes?
