Terry’s Locksmiths: A History of Excellence with BMW 1 Series Vehicles

For over 50 years, Terry’s Locksmiths has been serving the Gold Coast, providing expert locksmith services for a wide range of vehicles, including the BMW 1 Series. This popular model is known for its sophisticated engineering, and with it comes a variety of key and lock-related challenges that require specialized knowledge and experience. In this blog, we’ll explore Terry’s Locksmiths’ extensive history of working on BMW 1 Series vehicles, as well as some of the common key and ignition issues these vehicles face worldwide.

The Complexities of BMW 1 Series Locks and Keys

BMW 1 Series vehicles, like most BMW models, feature advanced security systems that can make key replacement, reprogramming, and ignition repair difficult without expert tools and techniques. Many models in the 1 Series, especially from 2004 onwards, use CAS (Car Access System), which requires specific knowledge to manipulate when dealing with lost keys, spare keys, or ignition issues. At Terry’s Locksmiths, we have decades of experience working on these intricate systems.

Here are some common problems BMW 1 Series owners may encounter:

• All Keys Lost Situations: When all keys are lost, a complete reprogramming of the security system is often required. This typically involves pulling out the CAS unit, reading the EEPROM data, and programming new keys.
• Spare Keys: Programming spare keys for BMW 1 Series vehicles isn’t straightforward, particularly for models with proximity keys. In many cases, special tools are required to read and back up data, including the removal of components like the FEM unit.
• Ignition Failures: As with most BMWs, the ignition systems in 1 Series models are sealed units, meaning they cannot be opened or repaired. If the ignition fails, it often requires a full replacement.

Terry’s Locksmiths: BMW 1 Series Expertise

At Terry’s Locksmiths, we have handled a wide range of locksmith jobs for BMW 1 Series vehicles over the years. Here are some of the key highlights from our job history:

Job Highlights

• Job 55162 (2012 BMW 1 Series): All Keys Lost
  Locksmith Kent worked on this 2012 BMW 1 Series, where all keys had been lost. Using the Autel tool, Kent successfully programmed an aftermarket slot key, using a 315MHz CAS3 system. The vehicle required a specific 3-button slot key, which was programmed without the use of proximity functions.

• Job 58695 (2014 BMW 1 Series): All Keys Lost
  In this job, Kent tackled a 2014 BMW 1 Series where the customer had lost all keys. The job involved programming a proximity key using the Autel tool. The key was a 3-button Prox Key using the FEM OEM system, a more complex system that required removal of the FEM unit and reading ISN data before programming the key.

• Job 69967 (2010 BMW 125i Coupe): All Keys Lost
  Locksmith Seb worked on a 2010 BMW 125i Coupe, where all keys were lost. This job required the removal of the CAS3++ unit and soldering to read the chip data. Seb used an Autel tool for this hard EEPROM job, successfully programming an aftermarket slot key for the customer.

• Job 84857 (2009 BMW 135i): Spare Key
  In this job, locksmith Henry provided a spare key for a 2009 BMW 135i. Using an aftermarket slot key supplied by Terry’s Locksmiths, Henry programmed a 315MHz slot key without the use of EEPROM, allowing the customer to have a spare key without needing the entire system to be reprogrammed.

• Job 87757 (2004 BMW 120i): All Keys Lost
  Henry also worked on this 2004 BMW 120i, which had lost all keys. The key was a 3-button slot key using a CAS3 system. Although the car was older, the job still required the use of advanced tools like Autel to read the key data and program the new key.

Common BMW 1 Series Key and Lock Problems Worldwide

Around the world, BMW 1 Series owners often face similar issues when it comes to keys and locks. Some of the most common problems include:

• Key Fob Failures: BMW 1 Series models, especially older ones, are prone to key fob failures. Over time, the key fob’s internal battery or circuitry may fail, rendering it useless. These keys often need to be replaced or reprogrammed by professionals.
• CAS3 Unit Problems: The CAS3 system used in BMW 1 Series models can malfunction, making it difficult to start the car or program new keys. When this happens, the CAS unit must be removed and reprogrammed, a task that requires specialized knowledge and equipment.
• Ignition Issues: As mentioned earlier, BMW ignitions are sealed units, which means they cannot be easily repaired. If the ignition system fails, it often requires a full replacement.
