Help!! VIP Alarm Key fob BS!!!!

Hey fellas,

So I just bought my first Tacoma. Apparently it has a VIP Alarm on it, and I was given two Keyless entry fobs that look like they were smashed by Thor's hammer, and then tapped up with a combination of electrical and standard tape, cause he felt bad. It seems like they function somehow if I fidget with it a little, but I really need to replace the case/shell for these things. The thing is, I can't find replacements for them ANYWHERE! I can only find a few key fobs with electrical components. I don't need the whole thing. I just need the plastic casing. Can you guys help me find this, or suggest an alternative? My alarm keeps going off every time I unlock my damn truck. Here is some info on my Taco and what Alarm system I think I have
2001 Tacoma 4x4 TRD/SR5 double Cab
I believe I have the VIP RS3000 alarm system
My key fobs are Grey and Diamond/Oval shaped
I need to replace just the plastic casing that holds everything
Here's a link to what my remote looks like -
