2001 Infiniti Q key question

Some yahoo says he has the keyfob and a new key for the above. Says someone just needs to get the key cut. A friend of mine was unsuccessful getting a code for her car key from the dealer. What's this guy not telling everybody? TIA GT

By 2001 most vehicles had transponder keys, meaning that in addition to the mechanical key there is an electronic chip inside the key that is interrogated by the car. If the transponder code doesn't match the key will turn but the car won't start.

Replacement key fobs are available from numerous sources that can be programmed to match the car either by having an original key and doing a sequence of steps with various switches in the car or with a programmer. However the mechanical key still needs to be cut to operate the physical lock.

So, two steps are needed to make an additonal key work. The transponder needs to be programmed to the car (or the car programmed to match the new transponder) and the key needs to be cut to match the mechanical cuts on the original key.

If you buy a replacement transponder key and follow the steps to program it, you'll still need to have the key cut on a key machine to operate the mechanical lock.

Many newer keys require specialized key machines to cut the side grooves. If your mechanical key looks like a standard key with the cuts along the top and bottom of the blank, any hardware store can cut it to match your existing key. If it's a side groove type, you may need to take it to a locksmith that has the right equipment. Locksmiths make a big profit on vehicle keys, but the programming equipment is expensive especially if they're making a key with all originals lost, as are the key machines for side-grooved keys. So expect to pay a premium to have it cut in this case, more than the couple of bucks for a typical duplicate key.

If you don't have an original working key expect to pay big bucks (at least three figures) to have a new key originated that both matches the transponder code and the mechanical lock.

There is one other thing to consider besides all the information Jay posted. If the key/fob/whatever operates the vehicle was bought from a cheap online seller, you are taking a big risk that the key and fob will accept the proper code. You will still have to pay for the programming of the items even if the code doesn't take. I highly recommend that instead of taking this risk and paying twice or several times, just spend the few extra $$ and go to a locksmith that specializes in automotive keys and uses OEM keys and fobs.
