I think this is going off topic already.

TS not locked both car keys inside his car.

TS lost both car keys.

The best option is to go back to Proton to get a duplicate set of keys and then change all the locks.

If your keys were landed in the wrong hands, then the car will disappear soon.

It is better to change them.
The person who got hold of your keys and remote can unlock your car and drive off easily (if you don't change the immobilizer & alarm system and the lock and the car ignition too).

You have to spend some money to safegurad your car.

You said it, not me.
Please read the first post again.

I thought now new cars no more this feature?

That means new cars from factory do not come standard.
Now that you fixed it after market, does it void the car warranty?

They void your warranty by introducing unknown object into their electrical system.
This was told by the salesman when I want to have this feature in my new car.
Not sure true or not.
Can you check with your salesman?

What car are you using? Good to have the ON/OFF switch.
I seen people add a gadget to the electrical system to enable the door lock after a certain spped.
