1. Which do you think is the problem?
Any of the two may be the problem. A defective remote or main unit. The main unit may be covered "too much" preventing recetion of signal from remote or wrong installation.
2. Is there away to activate manually the car alarm main unit?
This feature depends on the model and unit if the unit has this feature.
3. Pwede bang ipagawa ang remote key, or disposable lang ito?
There are some brands which have very good aftersales service that they can repair even the remote. For some ay patapon na ito. Try asking your vendor if they can repair the unitor sell replacement parts.
Dyan ka mag ingat sa mga reprogrammers na yan , they have access codes of ur security device that will make it vulnerable for them to jack ur car if they want to .
Viper alarms are good n reliable alarms , one of the good ones in the market right now . EIther u tripped some wires , wrong installation or nag short ito . Make use of ur warranty if meron ka pa or just get a new one .
may spare na remote ang viper dba? kasi yung akin model 300 may spare remote. na experience ko na rin yun ganyan sa akin. Ang ginawa ko habang pinipindot ko pinupokpok ko. Ang alam ko matibay Viper eh kasi yung remote ko nalublob na sa pool maayos pa rin. Nga pala may kilala rin akong gumagawa ng alarm.
