A key without a chip can be easily milled in a metal repair shop using a second copy - no one will even ask for the car documents. If you lose your only key,
a copy can be made from the door or ignition lock at a specialized company. You will be offered three variants there. The first is cheaper but more complicated. You need to dismantle the lock and take it to a workshop. The lock will be dismantled, its elements (pins) will be measured, and a duplicate will be turned out. The second way is more expensive - you can call a specialist directly to your car. The expert "considers" pins without dismantling the lock and will produce a key on the spot. In advance, of course, the master must verify by documents that you are the owner of the car.
