Steal then drive in Kampong or ulu places. Forever can't find.

Kesian no insurance payout.

Those who pannai pannai give car key to third-party like car wash guy, good luck. Insurance won't pay you.

Same with VIP parking, giving car key to hotel car park guy. Gone with the wind. U can start saving money to pay your bank loan and apply another car loan for new car

seriously? i wonder why not many cases like that, since it's easier to steal car this way rather than breaking into a parked car.

Car owners in Malaysia commonly pass their car keys to workers at a car wash and collect their vehicles minutes or hours later. Although the transaction is often unrecorded, we are used to this business style — surrendering our vehicle to a washer that doesn’t provide any written acknowledgement or receipt before and upon the completion of the transaction.

The underlying cause for this carefree attitude could be misunderstanding your car insurance policy. Maybe you have a comprehensive insurance plan, and you think it’ll save you from every trouble. But in reality, there are exclusions to what your policy can and cannot cover.

Now, let’s imagine a situation where a young woman named Aisyah visits a mall in KL to do some shopping. Aisyah wants to get her car washed outside the mall at an auto wash facility. Young Aisyah thinks it’s okay to pass her car key to one of the workers and leave the vehicle behind while she’s shopping in the mall. About an hour later, she returned to collect her car only to realise that her vehicle was lost.

One of the car wash attendants had mistakenly handed over Aisyah’s car key to the wrong person. Now that the car is lost, Aisyah does what every car owner would do. She contacts the insurer for help and files a claim for car theft since her comprehensive insurance policy covers theft. Unfortunately, the insurer rejected her claim because the incident had happened due to her negligence.

Break in is different.

Ur insurance will ask you to surrender your both fobs or car keys (usually in pairs). So If you fail to give even one, Ur insurance will take note and further investigate. They might even conclude you willingly give Ur key away so the onus is on you to prove.
