To reset the alarm on the 2007 Ford Expedition You have two options. You can pop the hood and disconnect the positive battery cable, then leave it off for about 30 minutes. This will make the power in the CPU drain, which will force the system to reset itself the next time it comes on. The other option is to pull the fuse from the fuse boxAnd wait a similar amount of time. This will do the same thing but will be more targeted. If You pull the battery it will reset a lot of things. If You just pull the fuse then it will only rest the alarm, but You will need to look at the fuse diagram and figure out which fuse is correct.
