**BMW CAS3+ CAS3++ E Series Key Programmer via OBD2 (PNP)**

1. Understanding BMW CAS3+ and CAS3++ Systems

The BMW Car Access System (CAS) is an integral part of the vehicle’s security system, responsible for key authentication and immobilizer functions. The CAS3+ and CAS3++ are advanced versions found in BMW E series vehicles, enhancing security to prevent unauthorized access. The main differences between CAS3, CAS3+ and CAS3++ are as follows:

These systems require specialized tools for key programming, ensuring only authorized keys can start the vehicle.

2. The Need for an OBD2 Key Programmer

Traditional key programming methods often involve removing the CAS module from the vehicle, which is time-consuming and can be risky. An OBD2 key programmer offers a simpler, faster, and safer alternative. By connecting directly to the vehicle’s OBD2 port, these programmers can communicate with the CAS module to program new keys without disassembly.

3. Key Features to Look For in a BMW CAS3+ CAS3++ E Series Key Programmer

When selecting a key programmer for BMW E series vehicles, consider these essential features:

• OBD2 Compatibility: Ensures seamless connection to the vehicle’s diagnostic port.

Example Scenario:

• Scenario 1: A shop programs 5 keys per month.
  • Investing: Initial cost of $3,000 + $10 per key = $3,050 for the first month. Subsequent months: $50.
  • Outsourcing: $250 per key x 5 keys = $1,250 per month.
• Scenario 2: A shop programs 20 keys per month.
  • Investing: Initial cost of $3,000 + $10 per key = $3,200 for the first month. Subsequent months: $200.
  • Outsourcing: $250 per key x 20 keys = $5,000 per month.

As the scenarios show, investing in a key programmer is more cost-effective for shops that frequently program keys.
