I am curious as to how modern car keys are made these days. It seems that the new 2015 Mitsubishi Mirage has a special key you need to get from the dealer.
Since I am the outdoorsy type, I am pretty hard on my stuff. I can see getting caught in a downpour with my car keys. I know the ones with the keyless entry in the heads are expensive to replace so I had a key made from a blank for $2, figuring this will be the only key I carry with me when I am outdoors and leave the others hidden somewhere safe.
The guy at the hardware store told me right off that this key will open the doors but probably not start the car. I said that is fine as I really just need to get into the car and don’t want to ruin the electronics in the other key of they get wet, etc.
Yep, he was 100% correct. I can get into the car with the spare key but it will either crank and not start or start for a second and then die. Apparently there is a chip of some sort in the factory keys that communicates with the car. There is only one keyhole on the driver side door for the entire car so obviously this is just a backup for getting in.
What happens if the battery in the key head dies? Will the car not start? I know some chips require power while many door access systems at buildings do not. The signal sent from the door energizes the device just long enough to let you inside the building.
This is a cheap car as has been discussed in great detail in the HUGE thread about the HUGE sale on them so cannot imaging it being a very complicated system compared to some on higher end cars. Even the “deluxe” model of this car has a push button starter that only works when a fob is within a certain distance. There is no mechanical component to the system.
How common is this in new cars to have a chip in addition to a mechanical key?
