What Types of Chrysler Key Fobs are Available?

A few types of Chrysler key fobs and car keys are available to choose from, depending on your car model. For instance: silver key on black car

Transponder Car Key

For older models of Chrysler, a transponder key may be the only option. They are not remote, so they don’t allow you to access the vehicle or start the ignition from a distance. Therefore, the transponder type is harder to use, but they’re likely to be the cheaper option for a replacement or a spare key since they have reduced functionality.

Chrysler Keyless Entry

Unlike transponder keys, keyless entry remote systems allow you to access your car from a distance and perform several other functions, including starting the ignition and opening the trunk. Vehicles often also make a noise you can hear when you lock them, making them easier to find. A Chrysler keyless entry system often comes with a separate car key that you can use in an emergency. Unfortunately, the fob won’t work straight out of the shop. Instead, it will need to be programmed before it can be used, which is not free and takes time. Call or email your dealer or an automotive specialist to arrange programming for your replacement key.

Features and Functions

Chrysler keyless entry systems have several great features:

Emergency Insert Key

The fobs are fitted with a spare car key, allowing you to unlock your Chrysler car if the fob breaks or the batteries die. Once you have purchased a fob, you will need to go to a car locksmith to get the key cut.

Remote Ignition Start

Modern Chrysler models allow you to start the ignition of your car without being inside the vehicle. By using a Chrysler key fob, you can select the option on the fob to start the ignition remotely. Not all Chrysler vehicles permit this functionality – call or email your automotive dealer or customer support to find out if your vehicle can be programmed to do this.

Trunk Release

You can use your key fob to open the trunk of your Chrysler, so you can load and unload items from your trunk without unlocking the rest of the car.

Panic Alarm

Your Chrysler car is fitted with a panic alarm function, which can be activated remotely using the key fob in the event of an emergency. The panic alarm activates the horn and headlights in the car for a period of 3 minutes, unless it is deactivated before 3 minutes have elapsed. blue classic car on brown field under blue sky during daytime
