Key fob problem need advice please

Hi mate, you would be better off buying a flip key from fleabay and programming it using the instructions in your manual.
It’s the way forward as the original key always fails after time.
Buy the flip key with blank, get it cut at a local key shop and use your original to help program it - easy job

As Bruce mentions, ditch the crappy stock key fob and get yourself a flip blade key fob instead from eBay.
As you've got the original key you can use the two key programming method which is simple enough to carry out then once the fob is working just swap over the transponder chip from your old key to the new one.

Most of these key fob are 433 or 434mhz...from speaking to a very well known auto locksmith I'm informed tjat the numbers are essentially rounded up or down depending on the manufacturer so both work anyway.

Yeah that key would work ok, just take it and your original to a key cutting outlet.
Here is a photo from my manual that I followed, just remember to keep drivers window open to make it easier

It's worth noting that Timpsons key cutting shops won't touch a customer's own blank keys as they can't guarantee the quality of the blank plus if it screws up their machines they're not covered.
Just find a little independent cobbler type shop and you'll be good to go.

Some do but they'll charge you a LOT more.

Have you swap the transponder chip from the old key to the new?

The synchronisation process will only match a new remote locking/alarm transmitter, and only then if there is a spare slot in the alarm system memory. There is an entirely separate immobiliser system transponder built into the key. It is a passive transponder, and is not on the circuit board. It's usually a small, delicate, glass pill-shaped thing, glued into the part of the key with the blade attached.

You need to dig this out, very carefully, without breaking it, and glue it into the new key, close to the blade, in the section that holds the blade, and not the bit that comes out, which is the alarm/remote locking transmitter.

If you can successfully match the new transmitter fob, it should work the remote locking and alarm, but will not start the car. You still need to transfer the immobiliser transponder into the new key.

If you can't get the new remote locking transmitter fob to be accepted by the car's alarm/locking system, then it may be the wrong kind of transmitter, or you may need to use VCDS or a dealer to wipe all the old keys out of the memory and program in the new keys.

Hi mate, let’s not get into a slagging match - I do know quite a bit about these cars by using and studying the SEARCH function.
Anyway, my apologies for not mentioning that you do indeed have to swap your glass transponder into new flip key. How many original keys do you have??
I had 2 + the RED key, I used the transponder from 1 of the originals.
Once you do this it will work - I’ve replaced 2 flip keys doing this and all worked for me.
Again sorry for missing out that detail.

Use a small screwdriver or the likes and gently prise it out - be careful not to crack it - then replace the new flip key one with this (the new flip key transponder will not be coded to your car)
