Need to program a new key fob for your 2007 Chrysler Aspen? Forget expensive dealership visits – you might be able to do it yourself! This guide provides a step-by-step process for 2007 Chrysler Aspen Key Fob Programming, directly from your vehicle’s owner’s manual.
Important Note: Two Valid Keys Required
Before you begin the programming process for your 2007 Chrysler Aspen key fob, it’s crucial to understand a key requirement. According to Chrysler, you must have two currently working and programmed key fobs to program an additional key yourself. If you only have one working key, or have lost all your keys, the DIY programming method outlined below will not work. In these situations, you will need to visit an authorized Chrysler dealer or a qualified automotive locksmith for assistance. They have specialized equipment to program new keys even without existing ones.
Step-by-Step Guide to Programming Your 2007 Chrysler Aspen Key Fob
If you are fortunate enough to have two functioning key fobs for your 2007 Chrysler Aspen, you can proceed with programming a new key fob yourself. Follow these steps carefully:
-
Prepare the New Key: First, ensure that the new Sentry Key transponder blank is properly cut to match your 2007 Chrysler Aspen’s ignition switch lock cylinder key code. This step is essential for the key to physically work in your ignition.
-
Insert First Valid Key and Turn to “ON”: Insert your first working, programmed key into the ignition switch. Turn the ignition switch to the ON position. Hold it in the ON position for at least 3 seconds, but no longer than 15 seconds. After this time, turn the ignition switch back to the LOCK position and remove the first key.
-
Insert Second Valid Key and Turn to “ON”: Within 15 seconds of removing the first key, insert your second working, programmed key into the ignition switch. Turn the ignition switch to the ON position again. Keep it in the ON position for approximately 10 seconds. You will hear a chime sound after about 10 seconds. Additionally, you will notice the Vehicle Security Alarm Indicator Light will start to flash. After the chime and flashing light, turn the ignition switch to the LOCK position and remove the second key.
-
Insert the New Blank Key and Turn to “ON”: Now, within 60 seconds of removing the second programmed key, insert the new, unprogrammed Sentry Key into the ignition switch. Turn the ignition switch to the ON position. After about 10 seconds, you will hear a single chime. The Vehicle Security Alarm Indicator Light will also stop flashing. To confirm successful programming, the Vehicle Security Alarm Indicator Light will then turn on again for three seconds and then turn off.
Congratulations! Your new 2007 Chrysler Aspen key fob is now programmed to your vehicle. The Remote Keyless Entry transmitter within the key fob should also be programmed and functional at this point.
Programming Additional Keys
If you wish to program more than one new key fob, simply repeat this entire procedure. You can program up to a maximum of eight keys for your 2007 Chrysler Aspen using this method.
What If You Don’t Have Two Valid Keys?
As mentioned earlier, if you don’t have two valid, programmed keys, this DIY procedure will not work. In this case, you will need to visit an authorized Chrysler dealer. They have the necessary diagnostic tools and equipment to program new keys for your 2007 Chrysler Aspen, even if you have lost all your existing keys. Alternatively, a qualified automotive locksmith specializing in key fob programming may also be able to assist you.
Important Security Notes:
- Replacement Keys: Only keys specifically programmed to your 2007 Chrysler Aspen’s electronic system will start and operate the vehicle. A key programmed to your vehicle cannot be programmed to any other vehicle.
- Caution! Always remember to remove your key fob from the ignition and lock all doors when you leave your 2007 Chrysler Aspen unattended. This helps prevent theft and unauthorized access.
- Lost Keys: If you lose a programmed key, it’s highly recommended to visit your Chrysler dealer to have all remaining keys erased from your vehicle’s system memory. This crucial security step will prevent the lost key from being used to start your vehicle. You will then need to have your remaining keys reprogrammed. Always bring all vehicle keys with you when visiting the dealer for Sentry Key Immobilizer System service or reprogramming.
By following these instructions, you can potentially save time and money by programming your 2007 Chrysler Aspen key fob yourself. However, always prioritize security and seek professional help from a Chrysler dealer or locksmith if you encounter difficulties or do not have the required two working keys.
