changing battery in 146 t-spark

are there any considerations for this?

my battery's toasted - just wondered if I'll screw the alarm / immobiliser by disconnecting power and putting a new battery in?

do i need to use the brown key when i've swapped the battery?

any input appreciated.

Did mine recently. The only problem that got me stumped was the ecu went silly when I put the new battery on....injector light and code light on.

After panicing and reading a few threads (thanks guy's), I simply connected the +&- terminals together with the battery DISCONNECTED. This drained the electronics and reset everything, job done.

Be careful not to knock the collection of relays hanging on the front of the battery tray, the wires and connectors there attract all sorts of spray, salt etc from the road and are just looking for an excuse to break

thanks for the replies. now done. was very straightforward. just disconnected the battery - washed and dried the battery tray (saves it going rusty with all the silt in the future!) and connected new battery up - everything worked without problems. excellent.
