Bizarre keyless entry problem...
 

I recently upgrade my 2004 Mazda 3 i(it was killed by a deer) to a 2005 Mazda 3 s. It came with a keyless entry fob. The unlock and alarm buttons work fine, but the lock button, seems to only trigger the alarm. It doesn't lock the doors, only triggers the horn to start honking. I have to press unlock to get it to stop, just like the alarm button.
I did some quick searching here, and using google, but didn't find any other cases or results.
I was thinking, maybe I could disconnect the battery for a short time, and maybe something will reset or something, but figured I would come ask here first.'

Any thoughts ?

Thanks.
