belt question and keyless entry qiut working
 

I have a 99 discovery. I need to know how long the belt is for it. It has a/c and the auto zone sold me a 91.5" belt and it is too long. The computer at the zone states it is the correct belt. I am 200% sure i installed it correctly. I put the old one back on with no trouble. Also the remote keyless entry just quit working today any thoughts? Thanks.

did you lay the belts out and compare them to each other, if they don't look the same just measure it and get one a bit smaller.
