Boot Beeping??

[Trick]

4 Beeps, i believe this is the alarm battery dying

Has anyone replaced the battery? Is it Easy to do? Any step by step guides? Pictures?

All help really appreciated!

Do a search mate, there is aguide somewhere but its a pain in the *** to do. Most recommend replacing the siren for a louder one for about £80, not sure what siren it is though.
