Should I change the Original Alarm???

[tsfatt]

My car is Toyota ... as you know the Toyota car is come with cobra with immobilizer alarm ... but it look only have simple alarm setting .. I mean no tilt sensor and sonic sensor .....

Do you think I can just add on these 2 sensor on it ... or change the whole set alarm (but will it look stupid change from better grade alarm to lower grade like those selling at Brother ).

if change whole alarm system is it still compatible with the car... currently alarm when drive 5 second the door auto lock.... but the most important is whether it will void warranty or not??? as you know Toyota will always push the matter to what ever thing that install by ur self (if happened electrical hair wire).

Anyone mind to share their opinion... tq.

I think u can jst add on this two sensor for ur cobra alarm.
Actually cobra alarm is not cheap lap alarm, it consider highend alarm.
Add more security is jst more safe or more alert to you.
