Chances of that happening are very remote and far-fetched but strictly technicaly possible.
If you really want that possibility avoided, you can ask the dealer to change the entire immobilizer/anti-theft system, the ignition and all door locks with a set of new keys.
medyo malaking gastos ata to sir ah... how about changing the security system outside casa aroung 1k+ wag lang ipatanggal ang Original ipaputol mo lang. at least mag alarm sya kung i try nya buksan ang Innova mo. Mas madali kasing nakawin ang sasakyan mo pag nandoon ang remote security sa kanila.

or change all door lock sa casa and security outside casa.
if you have budget change all na lang sa casa.
