Hello all fellow members of the community!
I would like for a piece of advise, as potentially some of you may have faced it as well.

I have changed my old ford styled key from my L322 2007 RR to the better looking flip key, picture attached of the old and new one.

The frequency matches, battery is fine, but for some reason whenever I press open/close key or tailgate open buttons, there is a delay in opening, maybe half a second or a second, sometimes really need to press multiple times for it to open, while on my old key I don't have any sort of problem, as soon as I press on the open or close button it does the action instantly. Hence, I'm not sure if the issue is with the key, transponder, or anything else.

another thing to add, with the new key I'm unable to open the windows remotely by holding the unlock button, while with the old one it's still working.

Did anyone have the same issue and if so how did you fix it?

thanks in advance,
Cheers
