[06MREvo]

So I haven't driven my evo in a couple days but last time i did my stock keyless remotes worked perfectly fine. I just took my car to the car wash and when I got back I went to lock my car with the remote and it didn't work at all. So i was like okay I've used the same keyless remote for the past 3.5 yrs so maybe the battery died so i grabbed my spare set and tried to lock the car and that didn't work either. Like i said the remote worked perfectly fine a coupe days ago then the car sat in my garage for a couple days, and now both of them don't work. Any suggestions on why both of my stock keyless remotes just quit working???
