Furthermore,
consider that if you have a locksmith come out and make you a new key outside regular business hours, the price may increase.
Finally,
If you have previously had your ignition cylinder replaced, which is quite common in older cars, this probably means that the code for the key may not be useful. In such cases, the key will have to be cut manually by a locksmith, or you will have to change the ignition again, and here the dealer can’t help.

Tips for Nissan Sentra key fob replacement – What to ask and verify before and after you get a new key fob:

Nissan Sentra key fob replacement – Emergency key, battery and chip
Very often when people get a replacement key fob, there are certain things they forget to check and ask the dealer or locksmith.
We gathered here the most relevant information and tips to make sure you won’t face a problem down the road.
First,
Make sure to get the key code of your Nissan Sentra key fob – Every key fob, has a unique code which locksmiths and dealers use to know the exact cuts to match your ignition, door and trunk cylinders.
Obviously, this code is different from one car to another. This key code costs money, and before the locksmith or dealer cut you a new key fob, they must pay to get the code from the Nissan database, which may cost them up to $100. Make sure you write down this key code and keep it in a safe place. In case you lose your Nissan Sentra key fob again in the future, it will cost you less to get a replacement, and the process will be faster.

Second,
Verify they cut you the emergency key, and that it works on the doors cylinders and trunk – Every key fob comes with an emergency key attached to it. The emergency key can be used to access the car in case the battery is dead.

Verify the emergency key is working smoothly on all cylinders

Finally,
know which battery your Nissan Sentra key fob has – These key fobs, like all key fobs, are battery operated. Make sure you know the type of battery you need and keep a spare one. (Nissan Sentra key fobs usually use CR-2025 or CR-2032 battery. That depends on which key fob you have).
Q: Can I get a Nissan Sentra key replacement by its VIN?
A: That depends on the year of manufacture of your car and the type of key you had.
The VIN gives dealers or automotive locksmiths the option of accessing the key code on file – i.e., to cut you a replacement key by code which makes the process fast and easy. There are however two things to consider:
- If your vehicle is older than 10 years, Nissan dealers will no longer have its key code record, so an automotive locksmith will be your only option to get a replacement key.
- For vehicles equipped with a transponder system and/or a remote/intelligent key/fob key, the codes should be available. However, as coding is required, you will have to either tow the car to the dealer, or have an automotive locksmith come and code the key on site.
