Challenges and Common Issues with Key Programming
If you see a blinking key symbol on your Volkswagen dashboard, it could be an indication of an issue with immobilizer programming or a damaged key. It’s essential to understand the basics of key programming to avoid inconvenience and monetary loss. In this section, we’ll highlight the common issues that arise during key programming and the factors that cause these issues.
Most Volkswagen cars made after 1999 require programming for the keys to start the vehicle. This means that the keys have an immobilizer chip embedded in them, and the car’s computer system must recognize the chip to start the engine. The process of programming is different from key cutting, which involves creating a duplicate key, but not programming it.
Transponder keys or remote keys have to be programmed to start the car. Programming a transponder key involves syncing the immobilizer chip with the car’s computer system, while programming a remote key entails programming the device to open doors and start the engine.
Remote keyless entry (RKE) and proximity keys with push-button start systems present unique challenges for technicians when diagnosing and servicing vehicles. If your RKE or proximity key fails to work, there could be a fault with the device or the vehicle’s security system.
When diagnosing a KESSY issue, technicians should take specific steps to identify the problem. They should replicate the issue to identify the fault, scan the vehicle’s computer system for fault codes, check for technical service bulletins (TSBs) that relate to the problem, and test the battery inside the key.
A VW key fob may stop working due to several reasons, including a dead battery, a faulty wireless entry board or Comfort Control Module (CCM), a damaged car antenna, or the need for the VW key immobilizer to recognize the key’s signal. Most of these issues can be fixed by replacing the battery or repairing the faulty component.
Cost-Saving Tips for Key Replacement
Losing or damaging your car key can be quite stressful and expensive, especially for Volkswagen (VW) key holders – this is due to the security systems embedded in modern VW car keys. However, with a few cost-saving tips, key replacement can be affordable and stress-free.
DIY guides are available for extending the range of VW key FOBs and for replacing the battery or circuit board. These simple tutorials can help extend the life of your car key and save you money in the long term.
VW cars produced before 2000 do not need programming for a duplicate key to work. Therefore, if you have an old VW car, it is much easier and cheaper to create a spare key.
To save money, one can purchase a cut key online from an OEM parts dealership and then have it cut and programmed by a VW dealer or automotive locksmith. This is an effective way to keep the costs of key replacement low, while ensuring the new key is programmed properly.
Making a duplicate key is cheaper than making a new key when all keys are lost. It’s much cheaper and less time-consuming to have a copy made than to have a new key ordered, cut, and programmed.
The key hack involves programming a new chip for Toyota vehicles that have lost all keys. This is not available for VW cars, but it’s important to be aware of alternative options if you were to lose all keys.
Ordering keys online and having them cut and programmed can save money. It is important to find a trustworthy source when ordering keys online, but this is a great way to save money as long as the key is programmed properly.
Lastly, it’s important to have at least two new cut keys programmed to avoid issues. If only one key is available, it’s always best to have a spare made to avoid any future hassle or potential emergencies.
KESSY and RKE Systems
Remote Keyless Entry (RKE) and Proximity Keys with Push Button Start Systems are becoming increasingly common in modern cars. These systems utilize advanced technology to provide added convenience and security to car owners. Volkswagen has developed their own version of these systems, the Keyless Entry and Start System (KESSY), which presents unique challenges for technicians when diagnosing and servicing vehicles.
| Volkswagen KESSY vs. RKE Vehicles | |
|---|---|
| System | Description |
| KESSY | Uses antennas and a push button to cycle the ignition and start the engine. The system uses the key as a low-frequency transmitter and requires the key to be present only inside the vehicle to start the engine. |
| RKE | Has a traditional ignition switch located on the steering column. |
Technicians must have an understanding of the particular system in each car they work on, as well as the features and functionality of the specific make and model. In the case of the KESSY system, there are a few key points to keep in mind.
KESSY Key Immobilizer Programming
The KESSY system uses an immobilizer chip within the key to prevent unauthorized starting of the vehicle. Therefore, when replacing or reprogramming keys, it is important to follow specific procedures to avoid damaging the vehicle’s electronics. Here are the steps for programming KESSY keys:
- Enter the vehicle with an already programmed key and close all doors.
- Insert the new unprogrammed key into the ignition and turn it to the “On” position.
- Turn the ignition off and remove the key, then insert the already programmed key and turn it to the “On” position within 20 seconds.
- Turn the ignition off and remove the key, then immediately insert the new unprogrammed key and turn it to the “On” position.
- Wait for the immobilizer light to turn off, then turn the key to the “Off” position and remove it. The new key should now be programmed.
It is important to remember that failure to correctly program a new or replacement key can result in a non-starting vehicle or even permanent damage to the vehicle’s electronics.
Additional Considerations
When working with Volkswagen’s KESSY system or any other remote keyless entry and start system, there are some additional considerations that technicians should keep in mind:
- Ensure that the batteries in the remote key fobs are checked and replaced if necessary. Dead batteries can cause the key fob to stop working and can be misinterpreted as a problem with the KESSY system itself.
- Be aware of any updates or software upgrades that may be available for the specific make and model being worked on. These updates can improve the system’s performance and prevent potential issues down the road.
- Pay close attention to any warning lights or error messages on the vehicle’s dashboard, as these can be early indicators of a problem with the KESSY or RKE system.
By following these steps and considerations, technicians can successfully diagnose and service the KESSY system and other remote keyless entry and start systems, helping to ensure that car owners can enjoy the added convenience and security these systems provide.
