Buick Key Fobs—Everything You Need To Know

There’s nothing more frustrating than discovering your Buick key has broken. Thankfully, buying fobs for your vehicles doesn’t have to be a stressful process.

Unlike a traditional car key, fobs don’t require you to physically insert them for them to work. Instead, clever programming allows you to lock and unlock your Buick automotive remotely.

To understand more about the types of Buick key fobs available and how to find a replacement for a reasonable price, read on.

What Types of Buick Key Fobs are Available?

The type of Buick key you need depends on the model of your vehicle and the programming of its doors and locks.

Transponder Key

If you own an older car or truck it’s likely that they will need a transponder key. They must be inserted into the doors and ignition, and are not remote.

This makes them harder to use than keyless entry remotes. However, because the programming is simple, the cost is often low compared to a Buick key fob.

Keyless Entry Remote

A keyless remote uses smart programming to interact with your Buick remotely. A customer can open and start their vehicle quickly and without contact.

If you are buying a new Buick remote you will need to use a specialist business to program it for your automotive. This means that the cost can be slightly higher than transponder car keys.

Smart Keyless Entry Remote

If your Buick is a newer model, you may need an advanced fob for the door. It is similar to the previous model but includes an uncut emergency key.

By using an OEM (factory GM) remote you can keep your vehicles safe. Ask your local dealership for more information on pricing, instructions and safety tips.

A specialist dealer can help you understand which type to buy, and will often code and program keys and remotes for you.

Useful Buttons

Buick key fobs are often fitted with a menu of helpful things as well as opening and ignition starting.

Many also include a panic alarm button. This button lets you quickly and silently call for a help service to your address to save you if you are in danger. This can help keep you safe.

Battery Powered

Key fobs are battery-powered. The size of the battery will depend on the brand and how new the item is.

If you are concerned about battery power or related issues you should talk to your local shop or Buick dealer. They can advise you on how long it will be until you need a replacement or may provide free charging of batteries.
