Apple keyboard - some keys not working

[617arg]

My wired Apple keyboard seems to be slowly losing keys. Started with the "delete" key, then one of the letters stopped working, and now the zero on the number pad area. The other zero is still working.

Any ideas what caused this and what I can do to fix it? I tried resetting the PRAM and SMC a few times, but neither worked. The keys were working a few hours ago.

Thanks for any help.

My new Mac Pro came with a couple of keys not working - Apple Store replaced it. Apparently not uncommon.

Weird thing - I just brought the keyboard home to try it on another computer and all the keys worked, at first. After about 2 minutes though the same keys are not working again.

Looks like I might have to get a new keyboard......
