Technology is made by human and also can be bypass by human. So, Im not shock, people can hack into system. Keyless entry still got its flaw, I see video it is even easier to hack and enter into cars as compared to traditional ancient car key.

Got one video I see on youtube, hackers follow closely ppl that just parking at the shopping complex on foot and amplify the signal, after that come to that ppl car, and drove off.

That is why security supplement such as gps tracking is important.
