Have golf 6 all keys lost to program new keys with Xhorse VVDI2 VW or VVDI2 full version, it is supposed to do service mode, please do as the below procedure.
—–On Kessy system you have to have Kessy Key brand new or Buy form Dealer.
If you use used key and chnage transponder car will start only if you put key close to coil ( where is normaly igntion tumbler is)
Remove dash , Read eeprom with programmer and save originla file.
Do service mode , I do this manual way, open originla file in Hex Editor add at line 1420 and 1430 all FFFFFFF.
This way you do not loose VIN and ABS stay same .
Write molded file back to cluster and put cluster in car.
On Kessy car you need to bridge at OBD pin 1 and 16 to get Ignition On.I would make with little switch because you will need to give ignition On/OFF when learn keys. Connect to cluster and read Sec. block. After susses , you need to write original eeprom to cluster.
VERY IMPORTANT : Do not EXIT any function till all is done.
If you have key form dealer then you can learn it right a way ,If you have New Kessy key then you need to read Immo block again , then make a dealer key .
After this press button ADD KEY. Then choose second option Learn Key with security code and follow instruction.. If you want to learn only 1 key you will see 0-1 then 1-1 .
At it end before you press OK on pop up message you need to turn ignition Off/On After THAT you see 1-1, then press OK on Pop up message and wait till 1-1 goes away. All keys are learn successful.
—–Other way if you have only Used key with new ID48 ,:
Remove dash , Read eeprom with programmer and save originla file.
Do service mode , I do this manual way, open originla file in Hex Editor add at line 1420 and 1430 all FFFFFFF.
This way you do not loose VIN and ABS stay same .
Write molded file back to cluster and put cluster in car.

Then read Immo block again ,
Make a dealer key first . After that press ADD KEY , then use frist option add key direct to immo block . After all done reset cluster ,remove bridge on OBD pin 1 and 16 . Put key close to Immo coil and start car.
That is service mode only needed for c32 c64 clusters. Please look at a photo which numbers need do service mode to do all keys lost
Tips to follow:
From 1 to 7. when you have all key lost .
#1 is cars with Micronas dash and for Service mode use VVDI and it needs in most cars made 2007 and up, Before that all key lost will work direct OBD.
#2 it is different service mode that I gave solution is other post
#3 to 7 my solution works in all of them.
Service mode only need if ALL KEy LOST, otherwise read IMMO data and make a KEy LEARn via IMMO DATA FILE
if you confuse what cluster choice, post cluster p/n and manufacture date.
Big thanks to @yugo45 on DK forum.
