Introduction:

Making a new key for Buick models takes time and money. While cutting the actual key require help from an outside source like the dealer or an automotive locksmith, programming the key can be done easily. The process of making a new key to start the car involved, basically, two phases:

 

A. Cutting a new key :
"Blank" Uncut Buick Key
“Blank” Uncut Buick Key

That means cutting a blank key to match the ignition and will be able to turn the ignition to “ON” or “RUN” position”.  You can call the dealer or a locksmith to cut the key for you. Keep in mind, you will have to provide proof of ownership and the VIN number.

 

B. Program the key –

Most of the Buick models made in the past 20 years are equipped with some sort of transponder security feature.

That security feature requires an additional action (programming the key) to start the car.

Either a locksmith or a dealer can program the key for you if you choose to.

However, the car will have to be towed there.

Alternatively, you can do it yourself. The instruction below shows you how to program the new key yourself without any special equipment or help from an outside source.

A step by step on how to program a new car key when all keys are lost, how to duplicate an extra key, troubleshooting, what you should know and more.

Most of GM models, Buick included, car keys can be programmed without a special programming machine.

Therefore, if you have an already cut key for any of these makes or models, chances are you can program it yourself without calling a locksmith or tow the car to the dealer.

Here we will give detailed instructions on how to program a new key, what you should pay attention to, troubleshooting and useful tips that can save you a lot of money and time.

 

A new master key can be programmed with a method called: “On Board Programming “

On-Board Programming is basically a way to program a new key or to add a duplicate key without a special machine.

All you need is a cut key that matches the ignition, enough battery, and this guide.

A few tips before you start the process of programming a new car key for Buick models:

Coding machine for Buick keys
Coding machine for Buick keys
  1. Once you program a new key, ALL previous keys will not start the car. In other words, if you find your old key after programming the new one, it will not work. Therefore, we highly recommend having at least two new cut keys and program both of them.

    Once you program a new Buick key all previous keys won't work
    Once you program a new Buick key all previous keys won’t work
  2. Programming Buick keys require about 30 minutes of battery life, without the car being on. Therefore, it is very important to make sure you have enough juice in the battery before starting the process. In case the battery dies during the process, the new master key will not program and you will have to start the procedure all over again.
  3. While most Buick models can be programmed with this method, we would recommend verifying the type of key with a locksmith or an additional reliable source that it is the right key.
  4. There are a few transponder keys (PK3, PK circle +, etc.) that work on Buick models. You must have the right type of transponder key that matches your model and year. Otherwise, the key will not program. You can check the right key for the exact make and model here.

  5. Remember to have the emergency key cut for your key fob. It is extremely important in case the battery dies on your key fob. The price for cutting the emergency key by the dealer or automotive locksmith is already included in the service.

  6. Make sure you make a duplicate key – regardless if you are coding a key fob or transponder key, it would be more cost effective to make an extra copy once you get your key coded as the locksmith or dealer are already doing the procedure with the car. The price for the second key should be 50% off the original.

    Remember to check the emergency key works in the door cylinder

  7. In case you only need a duplicate, you can have the option to add a key instead of erasing the current keys and then coding new keys. Ask the dealer or locksmith to add a key if you prefer that option.

Here is the procedure you should follow to program a new Buick TRANSPONDER  key – without the original:

  1. Insert the new cut and unprogrammed key you have into the ignition cylinder and turn it to the “ON” position. Make sure you look at the dash as the security light should illuminate as you turn the key. If the security light doesn’t illuminate it means you have a problem with your battery and you should charge or replace it.
  2. Once the security light is illuminated it will stay on for ten minutes. We suggest you have a stopwatch as well because the next step will have to happen within ONE minute and you don’t want to miss that.
  3. After 10 minutes, the security light will stop flashing, within ONE minute, you should turn the ignition cylinder into “OFF” position and then back to “ON” again. The security light on the dash should illuminate for an additional ten minutes and then go off.
  4. Within one minute, turn the ignition cylinder into “OFF” position and then back to “ON” again. The security light on the dash should illuminate for an additional ten minutes and then go off.
  5. Once the security light goes off after the 3rd time (total 30 minutes) the new key should be programmed and start the car. Keep in mind, ALL other keys will not work anymore. Now you can start the car. We highly recommend making a copy of the key.

I already have a working key, I just want to make a duplicate. What is the procedure of programming an extra duplicate key? (Transponder key ONLY – NOT A REMOTE)

The process of making a duplicate key, when you already have one or more working keys is fairly easy and therefore we recommend doing so.

 

Here is what you will need:
  1. A working key that can start the car.
  2. A cut key that you wish to program – make sure it has the right transponder value as your other key.
Remember to cut your key before you want to program it
Remember to cut your key before you want to program it
Here are the steps you should take to program an additional Buick key: (Transponder key, not remote)
  1. insert your original key – The one that currently you are able to start the car with into the ignition cylinder.
  2. Turn the ignition cylinder to “ON” position and right after to “OFF” position.
  3. Remove the original key from the ignition cylinder.
  4. Now you have 10 seconds to do the next step.
  5. Insert the key you want to duplicate into the ignition cylinder and turn it to “ON” position.
  6. Take a look at the security light. It should light up for about 2 seconds which will indicate the new key has been successfully programmed.

How to program Buick key fobs or remotes? The actual procedure to program a new remote key fob.

Buick remote car keys, also known as key fobs, smart keys or push to start keys, are the latest generation of security car keys.

GM, and Buick models, of course, included, is the only manufacturer that allows self-programming for remote key fobs.

Professional locksmiths call this process: “on board programming”. This process is also available for PK+, PK3, PEPS keys and more.

There is, however, a difference between programming remote key fobs and regular transponder keys.

Below, we outlined a step by step process how to program your new remote key fob. Simply follow the steps and have your new remote ready to go in no time!

Before you start

Remember – This process will erase all previously programmed remotes!

The process of programming remote key fob: (This process is to program a new remote – NOT A DUPLICATE!)

 

First,

Make sure all doors are closed and stand outside next to the driver side door. Take the emergency key out of the remote and insert into the bottom of the plastic cover, located at the bottom of the door lock cylinder on the driver side door lock. You can see an example below.

Second,

Take the key out and insert it into the actual door lock cylinder of the same door(driver side).

The following step should be done within 10 seconds – turn the emergency key six times to the left – that would be counter-clockwise. If you did it right, a message on the dashboard should say: “remote learning mode” or ” remote learning in progress” (depends on which model you try to program key for). The message usually stays on for about 20 or 30 seconds.

Third,

Once the programming mode is on, you should see a notification: “Press the push to start button” which is the button you use to actually start the car. Push it once. (It can take about 10 minutes to appear, depends on your make and model). The notification will then indicate that “remote learning mode is in progress”. Repeat steps 5 & 6 2 more times.

Fourth,

If you did everything right, the third time, you should see: “ready for remote one”. Put the first remote you would like to program in the cup holder or in the armrest. (It depends on your make and model. If you are not sure, you can ask the dealer where is it located.) Below is an example:

Placing the key fob in the right place is crucial for a successful programming

Fifth,

Once the remote is in the right place, press again on the push to start button. The first remote is programmed and ready to go. You should see a notification that the car is ” ready for remote number 2″. Place the second remote in the same spot and press again, push to start. In case you did it right, you will see a notification:” ready for remote number 3″.

Finally,

Press and hold the “push to start” button for additional 20-30 seconds. Once the screen has gone blank, its time to test both remotes. Press the lock & unlock button on either one of the remotes. If the car responds, you are ready to go.

A: VATS keys, PK3, PK3+ etc are chipped keys or transponder keys for different years for Buick models.

In other words, all these keys need to be programmed to start the car. They have an additional security feature that reduces the chances of an unauthorized key to start the car.

The procedure for these keys explained above and is most of the time the same and shouldn’t be complicated.

The exception is the VATS key, that doesn’t require any programming, only having the right chip number in them.

How can I know if my key is PK3 or just a regular key?

All PK3 keys are transponder key. Therefore, you will see a black cover at the top of the key. In addition, it will be marked on the key itself “PK3” “PK3+” etc. Here are a few examples:

What are the security issues that may occur with PK3 keys? How can I know if something is wrong?

The main issue with PK3 is, like with any other transponder key, is programming. There is a very simple indication if you did something wrong during programming and/or if you have the wrong chip key.

Programming a new Buick key, assuming you already have a blank key, basically involves two phases:

 

1. Cutting the key or remote so it will fit your car’s ignition.

Buick door cylinder - key must match
Buick door cylinder – key must match

Before the key can be programmed, it needs to be cut to fit your car. The way an automotive locksmith or the dealership do that is by “pulling” the key code, using your VIN from the database. This cost them money and therefore, they charge you for it. (Unlike when you already have a cut key and just need a duplicate)

 

2. Program the key or remote – to actually start the car. (You can save money by programming your key yourself. See instructions above)

The programming procedure is simply a process to let your car know that the new key is “authorized” to start the car. That being done by connecting a programming machine to your car’s computer.

Both the dealer and an automotive locksmith will have to do the same thing, however, the prices vary:
