1) You do not announce to the whole wide world if you lost your key.
2) Once you realized your lost car key, immediately duplicate a copy from the spare and use the duplicate ONLY.
3) If it's a theft loss, you can't claim with a spare key. Hence, you only use the duplicate key, keep the spare key at home as original. In any event, you can use the spare(original) at home to duplicate another key.
4) Report polis upon lost of key
5) Get original replacement key, reset immobilizer and alarm coding. From what I heard, it costs up to RM600 do reset the whole thing(include RM200 for original key + immo chip)
6) Report polis upon completion of alarm & immobilizer reset.
7) Finally, send in polis report from 4, photocopy receipt from 5, polis report from 6 to your insurance company. Report as none claim accident notification. Just to tell them you have lost the key, changed the alarm code and immobilizer. They shall not void your insurance claim by any chance

The above are CORRECT way for proper insurance coverage. As for bawah pokok style:
1) Get a replica for RM35
2) Duplicate immobilizer chip RM90
3) Drive with duplicate key only, safeguard the spare key
4) Don't tell anyone, don't mention it.
5) If so happen kena theft loss, use the spare key to claim insurance. The rest of the story, you pandai pandai make it up. I don't wanna kena tahan because teaching people to make fraud claim
