Hello, my 4Runner SR5, 1998 147k is having problems with its security system. I thought at first it was the battery in the clicker on my key chain (original one from 1998 I think) I replaced it and I'm still having the prob.

When I attempt to "arm" it lets out a long beep as if it was stuck for about 6-7 secs),,,normally it's just one or two short beeps. Can anyone help?

ty all in advance....
