Critical steps and tips:

1. Disconnect the car's battery before starting.

DIY is possible for mechanically inclined individuals, but professional installation is recommended. Programming the module requires specialized equipment and knowledge.

You have two main options when buying a replacement theft control module: Used OEM and New Aftermarket.

Used OEM: This is often the best value. You get a genuine factory part that was originally designed for your BMW or Mini. These parts are typically tested and inspected to ensure they are working properly. The price is significantly lower than a new part.

New Aftermarket: These are brand new parts made by third-party manufacturers. They are designed to meet or exceed the original equipment specifications.

Parts commonly replaced or checked at the same time:

• The car battery.
• The key fob battery.
• The wiring harness to the theft control module.
• The immobilizer system.

Replacing related parts can prevent repeat failures because a problem with one component can sometimes damage others. For example, a faulty battery can cause electrical surges that damage the theft control module.

The theft control module typically lasts 10-15 years.

Factors that affect longevity:

• Exposure to moisture or extreme temperatures.
• Electrical surges or shorts in the car's wiring.
• The overall condition of the car's electrical system.

Here are typical price ranges for theft control modules:

• Budget: Used OEM - $50 - $150
• Mid-Range: New Aftermarket - $150 - $300
• Premium: N/A (New OEM is not available)

Labor cost for installation can range from $100 - $300, depending on the shop and the complexity of the job. Programming the module adds to the cost.

Total job cost estimates:

• DIY with Used OEM: $50 - $150 (plus programming if you can do it yourself)
• Professional Installation with Used OEM: $150 - $450 (including programming)
• Professional Installation with New Aftermarket: $250 - $600 (including programming)

For BMW and Mini vehicles from 1995-2010, some common issues related to the theft control module include:
