Since the battery in my 2002 XLE is orgional, thought it might be a good idea to change it for preventive maintiance before I get a big surprise some day. Since this car is equipted with ignition security system, door locks etc. is there anything that I should be aware of or do before disconnecting the battery. I'm aware that radio and clock, etc will loose memory and that I should have all doors unlocked & at least drivers door opened so not to be locked out. Is there any other precautions that need to be taken so not to be surprised ? Then just change the battery, right ?

P.S. this is the first car I've had with such a security system.
