The CD5442 is a 2002 year model (I think) and could still be under the 3-year warranty if it was installed by an authorized dealer...obviously depending on when you bought it.

JM, Whats up homie? Been a while....
I had a 5303(?) and it did the same thing. Like John says, it's should be under warranty. If not, I may have a remote laying around for one. I'll send it to you.
