I've changed batteries before (on a '98 with Meta alarm) and had no problem with immobiliser. Also have changed alarm siren which has built in battery and no problem there either.

What age is your car and what alarm system does it have?

Went to go to the Suffolk meet today - damn battery flat! Not totally flat - all warning lights coming on but Alarm has gone to sleep so no rem. lock/unlock. Car in garage, no access to battery direct so tried a jump to the alternator terminal. Not cranking over. SO have connected up proper charger (to alt. terminal) and left for a couple of hours on high charge rate. Still won't crank! Fuel pump priming, but nothing from starter. All was fine last time, no starter problems or symptoms. Is it the immobiliser?

dont think you should charge through alternater might lead to more problems undo 13mm bolts under passenger side move battery forward charge that way,your battery might be totaly shagged this may indicate why it wont start after charge,get a new one and retry,if its a later chim 1997 the immobilisor should be ok,just make sure that you dont disturb the wiring ie make sure avery thing is tight when you put it all back together.

doutful as the imobiliser works on the fuel pump relay. If the imobliser was at fault the fuel pump would not run. (meta 99 alarm) Sounds like a starter motor problem which could explain the flat battery in the first place.

This happened to me a month ago. Thanks to PH got it sorted.

You will need to disconnect the battery - fully charge it - reconnect - operate the blipper a few times to reset - hey presto!

Bit difficult with the nearside up against the garage wall. Although I wouldn't recommend it in writing, I have full confidence and sufficient experience to ensure this is safe.
