Why doesn't the keyless entry unlock passenger doors on an 04 Toyota Tundra?

Question

The keyless remote for my 2004 Toyota Tundra will only beep 1 time. I can't get it to beep 2x's to unlock passenger doors. Sometimes it won't even beep once. I tried the other remote and got the same symptoms. I replaced the battery in the remotes, but it didn't solve the problem. Is there a relay or somthing that went bad?

Answer 1

You most likely have a bad alarm module assembly....

Answer 2

take it to the dealer to check it out...its suppose to unlock all doors when you press it twice....
