GM Ignition Tip

As a locksmith technician key origination level of difficulties tend to vary a lot from vehicle to vehicle. Most of the time the ignition cylinder would need to be access and removed in order to look at the code that will allow to originate a new key. However, I found out that on some mid 90's GM vehicles, having a working door key can make the job much easier. From my experience I can confirm the above is true for 95-00 Oldsmobile Aurora models. It seemed to me that the bittings for the door key are the same as for the ignition key. The only different is that the door key is usually being cut using a standard GM 10 cut blank and the ignition key is a VATS 10 cut blank key.

With the information I got from GM, that model intended to have the key fits all models. According to GM, there is a reason that there are two keys being used for the vehicle(one for the door and one for the ignition). The reason would be since they couldn't figure out how to make the VATS ignition key to open the door because the VATS chip seem to interfere with insertion of the key inside the lock. Because of that, GM decided to use two different keys that would work using the same bittings. This may work on mid to late 90's various Buick models.
