bros... just a few questions regarding problem with my car alarm:

can't activate the car alarm

1. which do you think is the problem?
a. remote key - note: batteries replaced with new one already
b. car alarm (main unit)

2. is there away to activate manually the car alarm main unit?
- to know if it is busted or not, thus, remote key is the problem.

3. pwede bang ipagawa ang remote key, or disposable lang ito?
- can i just bring it to any electronics technician?

the brand of my car alarm is viper (don't know w/c model though)

thanks for reading (hopefully - replying also!) my post.
