my stereo got fixed but remote no longer work?

hi all my car stereo was fixed under warranty. Came back worked perfectly. but original remote control does not work anymore. I am guessing this deck is a replacement deck. Do i have to reprogram the remote ? can you tell me the steps .my deck is a pioneer premier p600ub. Thanks alot

If the replacement is the same as the original model then the remote should work, check the remote battery.

ANY pioneer remote should work on any pioneer headunit

Thanks guys it turns out the battery is dead on my remote. after replacing it, the remote worked great again. TY!
