Plenty of people on Ebay with the kit to clone the keys immobiliser chip and sync it to the central locking, also sellers of keys cut to a photograph, if you are lucky you might find one that does both cheaply.
Beginning of the confinement I paid £40 or £50 to an Albanian to supply, cut and program a key, parked outside what looked like a squat in a dodgy part of London he had taken my key to cut it and I wondered whether he was going straight out the back gate to somewhere else to return later to steal my car that I could no longer start!!!
It all ended up fine, he had some programming of the key to do in the vehicle after using my one in the ignition, the kit he used was the best a car thief can buy 🤣
You do not want to go down this route if there is a possibility that an original key could be in the hands of someone dodgy, or should I say dodgier than the dealer who sold you the car.
