My wife and I now have near identical cars. Is it possible to have the proximity keys made the same!! About to head to the dealer but just want a heads up. Thanks

here is when this would ne a problem. like your wive goes shopping to supermarket your at work and need something not knowing and also head to the same carpark. on the other row of cars 5 meter away . you go in the shop lock your car with tools radar detector etc loads of valuables in the car, Your wive comes back unlocks hercar and drives off. then your car will be unlocked also for anyone to empty its content. So i would say they would not want to make them the same or your insurance would not pay out at all all sorts of reasons

Except when you unlock you vehicle with remote locking and don't open a door within a minute or so it will re-lock itself, fairly standard across most makes and models

You could have both keys programmed to the cars, if they run the same system. There will be no extra security risk.

I don't think so, at least not at reasonable cost. The key is programmed to the ECU, not the other way around, which can't be changed.

vw should be easy to programm same keys to 2 cars also as they run all and everything over obd2 diagnostic including tuning maps on edc16 for example but doubt a dealer got the knowhow to do this or even the interest. also see thisto show it can be done http://hackaday.com/2010/07/13/key-fob-programming/

That's why it can be done. They can take several keys in the memory, because, ya know people do lose 'em.

could be expensive if one of you lose a set.

Hi. If it is a VW, then this cannnot be done. When a key is made, the number is stored by VW and recorded to the immobilizer number and then can only ever be programmed to that cars Identity. You cannot programme a key to another after that. Most European cars are like this.

If it's a Lexus and you are talking smart key fobs! both cars are the same model and year! then yes both cars can have the same fob signed on to both wireless lock and engine imb systems.
