Lost Car key with Alarm

[dr. d]

Need expert advise.

I own a mitsu lancer pizza. Kanina lang, nawala ko yung key with alarm. Not sure kung saan ko nawala and worry ko eh baka manakaw kotse. Question is, ano pinakamagandang gawin sa sitwasyon na ganito? Since kayang patayin yung alarm kung sakali and madali din buksan kotse since may manual key, ang naiisip ko lang is lagyan ng steering wheel lock, pero di ko alam kung gano kaeffective eh. Long term naman is palit susi, but may idea ba kayo magkano magagastos sa ganon?

Thanks sa magbibigay suggestion.

Note: open garage

ideally, replace alarm and all locks with new combination.

un-ideally,
magpa-xerox ng bagong susi.
buy steering wheel lock for deterrent effect.
