We’re sure you’ve all been in the same situation at some point or another, you cant find your keys in your bag and you spend 20 minutes standing next your car wondering if you actually have your keys with you or not, you start to worry that you left them somewhere. BYD scientists have probably been in the same situation before and have come up with a solution, the key watch.

The new BYD watch features a keyless intelligent key into molded into a  quartz watch to receive and sends electro-magnetic signals to the car and relies on radio frequency and ID recognition technology. The car owner only needs to wear the watch in the proximity of the car to gain access to the car and presumably turn on the engine as well.

When developing the watch key, the biggest problem was solving the problem of interference,” said Mr Wang, the engineer. The solution to this problem benefitted from SBID technology, one of BYD’s IT patents. It coats plastic with metal. The technology is proprietary to BYD, who own independent intellectual property rights. BYD has already applied for 36 patents in China, of which 9 have been granted, and it has applied for 21 patents abroad. This technology has already been widely used in the BYD OEM Nokia and MOTO mobile phones. With this technology, a high frequency antenna can be put in the plastic base of the watch, preventing the antenna from being obstructed by the base, effectively enhancing the signal. At the same time, the base can fix the watch mechanism and circuit board, killing two birds with one stone.

BYD are serious about their expansion in the watch business and will introduce different styles and ranges in the near future as part of a drive to push the companies technological abilities. In addition the Key Watch BYD also created a system that allows car owners to remotely start their car, open the doors and turn on the air conditioning system prior to the car owners arriving at their cars.

Aston Martin owners might not be entirely impressed, the company partnered with watch maker Jaeger-LeCoultre in 2008 which saw the two create a 37,000USD watch that is capable of opening the doors of your Aston Martin DBS.
