Keyless Immobiliser Door Lock System

The immobiliser system in car locks can be applied to home doors. Instead of carrying keys, special rings with immobiliser chip can be used and when you touch the door handle with your special ring on your finger, the door unlocks. The advantages of this system are: 1) Rings can not be duplicated in regular key-makers as traditional keys, only producer can duplicate your ring since the code in your immobiliser chip is unique to you. 2) Traditional locksmith methods, which are also used by thiefs, can not open your door lock since there is no mechanical key system on your new immobiliser lock. 3) Since every person in the household has his own ring on his finger, the probability to lost the ring is lower than the probability to lost the keys in your bag or pocket. 4) Ring was worn on your finger and unless you wear out the ring outside your home, it is imposibble to get the ring stolen. 5) From engineering point of view, rings with immobliser chips can be easily manufactured. Those chips are very small in size (can easily fit in a very thin ring ), very durable (operates for many years), need no service and also very cheap in price. Keyless immobiliser door lock system is very reasonable and can be successfully applied to any door. 6) As a final word; this system is more realistic, more reliable, much more safer and clearly cheaper than both traditional mechanical key-lock systems, and new developing image-speech processing solutions.
