Just thought I would post this as ref
Key on our Polo Blue GT (same key as 7 or 7.5)was not always locking or unlocking on the buttons.
Called VW to get price on the buttons section as thought this was the problem hopefully, for a laugh and sat down for a price.
"You can't buy any parts you need the complete key its £374and £89 to code it" said the grumpy tw#t in parts!
After laughing at his stupid price I bid him a cheery goodbye! 🤣🤣
Ordered this
https://ebay.us/m/aihdj5Came 2 days later fitted perfect and key is like brand new well worth a go if anyone has any issues or just needs a key refresh👍
Not connected to ad in any way as you can get them elsewhere maybe even cheaper but just thought I would share the info.
