i cant pop my trunk viper alarm

i got a real dalima i couldnt open pop my trunk in my 2000 caviler which wouldnt be a huge problem if that wasnt the only way i can put gas in my car yup i put my gas in my car by opening the trunk becuase the gas cap was shaved off and moved in my trunk.and im realy low on gas.

anyway i bought the car with the pop trunk and viper alarm in it already it worked fine for about two months and now just haveing that proplem it now seems that the aux is just not working no more it doest do the silient alarm anymore and when i hold the aux to pop trunk nothing happens then i let it go and i hear beebing noises and thats it. the lock and unock button works good once and a while it takes longer to disarm the car then usual i have to click it like three times for it to disarm i dont kkonw if its the remote or what i changed the battery about three times already.

let me know what yall think so i can get the trunk oppen or if theres a way to manualy pop it so i can get gas in my car. i can get in the trunk threw the back set and thats it.
