Coding in a fob

Does anyone have a concrete method for coding in a previously working fob? The battery died and whilst the car will start with it on left of steering column it says “key absent” not “key not detected”
It doesn’t sync the key fob.
any advice ?

Was the new battery a Duracell. I have heard some people have had issues with them due to the bitex coating they put on them causing a poor connection. Cleaning with Alcohol or nail varnish remover can sometimes get them working
I checked it with a multi meter as someone above said a similar thing but thanks anyway
