No key, no claim
If you want to claim for your car in case of theft then there is something you must consider to get your claim. Your claim can even be rejected if you don't have the two car keys. These need to be the two original car keys that you get when you purchase a new car.
Why does the insurer ask for both keys?
An insurance policy covers theft and not negligence. If the car was not stolen because of the owner's negligence then providing both the car keys proves there wasn't any negligence on the part of the owner. At the same time, it also acts as proof that there is no intention to defraud the insurance company.
Trying to submit keys of some other car
One might get into trouble if he/she submits a fake car key. Since any stolen car incident involves FIR followed by the police investigation, if the police find the car and insurer gets to know about the fact that the keys are fake, then it can be a trouble for the individual.
What best practice you should follow
Normally one car key should be used to access the car lock system and when it gets damaged/stolen or worn out, then you use the other one.
1. One must keep the worn out/damaged car key safe since it can help you get the car claim easily.
2. Taking a car key replacement insurance rider with your car insurance policy can help. In case of lost key replacing the car, lockset is advisable.
Points to note
On losing your car keys, you need to report it to the police and get an FIR (First Information Report). Also, inform the insurer about the loss of key(s) before getting another key made in case you are getting duplicate keys made instead of getting the entire lockset replaced.
At the time of filing the insurance claim, apart from submitting both the keys to the insurer, you must keep the following things handy: insurance policy details, vehicle details, and copy of the FIR.
