 The CAS3 (Car Access System) module is a critical component in BMW and MINI vehicles, responsible for managing the immobilizer and key recognition. When the CAS module fails, it can lead to issues such as the car starter not working, key recognition problems, or even water damage. In such cases, cloning the CAS module to a new one is often a faster and more cost-effective solution than repairing the original unit.

• In BMW vehicles: The CAS module is typically located at the bottom left side of the steering wheel.
• In MINI vehicles: The CAS module is found under the upper dashboard trim.

It’s important to note that there are different versions of the CAS module. Always check the markings on the case and the processor to ensure compatibility.

CAS modules can fail for various reasons, including electrical faults, water damage, or wear and tear. For example, in one case, the ED07 diode burned out, damaging the circuit track. While repairs are possible, cloning the module to a new CAS3 is often a quicker and more reliable solution.

Disassembling the CAS module is straightforward. The module is held together by plastic latches, with no bolts or sealant to remove. Once opened, the board is coated with a protective varnish, which can be easily removed using a specialized liquid like Mechanic.

The cloning process is similar across tools like Autel and Multiprog. The general steps involve reading the data from the old module and writing it to the new one. Here’s a breakdown of the process using two popular tools:

• Method 1: Solder wires to specific points on the board. This method is quick and straightforward, taking about 5 minutes.
• Method 2: Use a special CAS3 adapter for a solder-free connection.
  MULTIPROG is known for its fast reading speed and user-friendly interface. It’s updated frequently, with the Xhorse team constantly adding new features.

Here shows method 1. Solder the wires as shown in the diagram. It takes 5 minutes and is not particularly difficult. MULTIPROG reads quite quickly. The wires are better than in Autel.

• Autel offers flexibility, allowing you to work with either a computer or devices like the Autel IM508/IM508S/IM608.
• The Autel IM508S requires an additional resistor for connection, though some users have reported success without it. PC software does not.
• While Autel reads slightly faster than MULTIPROG, the difference is negligible. However, the PC version of Autel hasn’t seen updates in a while, and the IM508S requires an annual subscription for full functionality.

 This article will walk you through the process of programming a smart key for the 2023 Hyundai Santa Fe using the Lonsdor K518 Pro, a tool that has proven to be reliable for such tasks.

This particular job was the third Hyundai I had worked on in a week, with the other two being a 2022 Santa Fe and a 2023 Tucson. Both vehicles presented their own set of challenges, particularly when it came to programming and pulling the PIN codes. For the 2022 Santa Fe, I used the Auto Pro Pad to retrieve the PIN, while for the 2023 Tucson, I had to obtain the PIN directly from Hyundai. These experiences highlighted the importance of having the right tools and knowledge to tackle different scenarios.

For the 2023 Santa Fe, I decided to use the Lonsdor K518 Pro, the same tool I had successfully used for the previous two vehicles. The process began by accessing the “Immo and Remote” section on the device and selecting Hyundai from the list of manufacturers. The next step was to read the PIN code (Read pin ID47 smart key), which is essential for programming the new smart key.

After selecting the appropriate model (in this case, the 2023 Santa Fe), the Lonsdor K518 Pro prompted me to turn the ignition on and off, open and close the driver’s door, and activate the hazard lights. These steps are designed to keep the body control module active, which is necessary for the device to communicate with the vehicle’s system. Despite some initial hiccups with the Wi-Fi connection, the device successfully pulled the PIN code after about 25 seconds.

With the PIN code in hand, the next step was to program the new smart key. It’s important to note that when programming new keys, all existing keys must be present, as any keys not programmed during this process will be erased from the vehicle’s system. In this case, the customer provided two keys, both of which needed to be programmed.

The Lonsdor K518 Pro guided me through the process, prompting me to confirm the PIN code and then prepare each key for programming. The device instructed me to press the start button within five seconds of confirming the PIN, and after a few moments, the first key was successfully programmed. The same process was repeated for the second key, which also programmed without any issues.

After programming, it’s crucial to test each key to ensure they work correctly. In this case, both keys were able to lock and unlock the vehicle, and the rear hatch opened as expected. While I didn’t test every feature of the key (as the customer had supplied the key itself), the primary functions worked perfectly, indicating a successful programming session.

Programming a smart key for a 2023 Hyundai Santa Fe using the Lonsdor K518 Pro is a straightforward process, provided you have the right tools and follow the steps carefully. This job was another win for the Lonsdor K518 Pro, which continues to prove its reliability in handling modern vehicle security systems.

Xtool is also powerful for Renault key programming. Here we show how to add a spare key to 2016- Renault Master with Xtool X100 PAD3/IP616 etc and KC501.

Go to Special Function- Key Programming- Select by Model- Renault- Master- 2016 onwards.

Select Program Keys.

Switch ignition off and remove key.

Read pin code successfully.

Hit OK to program key.

Follow promotes to program 1st and 2nd key.

Programming completed in 2 minutes.

Both Xhorse and KYDZ released MQB48 adapter for VAG MQB48 NEC35XX immo data collection. With these adapters, we don’t need to disassemble the instrument but only the key. With low risk, simple operation, it can add keys for most MQB48 keys.

Which MQB48 adapter is better?

VVDI MLB Tool MQB48 Adapter

Pros:

No token or points to collect data.

Large coverage. Supports VDO, NEC35XX, JCI RH850 clusters. Prox, bladed, digital cluster.

Don’t need to remove cluster to read data.

More stable, better support and has more positive feedback.

will generate MQB remote using xhorse key tool and MQB remote.

Cons:

Need to replace an enhanced chip to use MQB48 function (check instruction here,  but don’t need to switch back to use MLB function again).

MLB Tool only collects data, you need key tool plus or vvdi2 to generate dealer key and learn key.

Cannot directly show cs, pin code. need to load file to key tool plus or vvdi2 to show cs and pin. 

Need to remove just 1 capacitor and solder back.

KYDZ MQB48 Adapter:

Pros:

Don’t need to modify hardware to use the mqb48 adapter.

It will show CS and pin.

No need to remove capacitor on key board.

Cons:

It is separate hardware. To collect data for MLB and MQB48, you need 2 separate hardware adapters. while Xhorse just 1 device.

Have to pay 10-15 dollars for the token. Extra $10-15 per token after used up.

Generate MLB dealer key with MLB tool, then program key with its MQB programmer.

Inmodata 16 byte from the xhorse key does not ask you token, stick with xhorse.
