Terry’s Locksmiths – Expertise in Smart Car Ignitions, Keys, and Door Locks

Smart Cars, with their compact design and unique security systems, present a specialized challenge for locksmiths. At Terry’s Locksmiths, we possess the expertise required to service Smart Car ignitions, keys, and door locks, offering solutions for all key-related issues. Our skilled technicians are experienced in key programming, remote coding, and lock repairs, handling common models like the Smart Car Fortwo with precision.

Understanding Smart Car Key Systems

Smart Cars utilize advanced security systems with transponder keys and remote functionality for keyless entry. The Smart Fortwo, for example, uses ID46 transponder chips and requires specific programming steps to ensure proper key functionality. At Terry’s Locksmiths, we leverage specialized tools like the Smart Pro, Autel, and VVDI Key Tool Max to perform precise programming, ensuring seamless integration with the vehicle’s security system.

Common Smart Car Models We Service

1. Smart Car Fortwo – Addressing All Keys Lost Scenarios
   Dealing with all keys lost scenarios on a Smart Car Fortwo requires a thorough approach. For a 2011 Smart Car Fortwo, our team utilized the Smart Pro to program a non-remote key. The process involved cloning a transponder chip using a KDiy smart 315 remote, which worked successfully despite initial challenges with other transponder types.

   • Challenges: Programming failures with certain transponder chips, requiring multiple attempts and alternative approaches.
   • Tools Used: Smart Pro, VVDI Key Tool Max, KDiy remote programmer
   • Tech Note: The emergency door lock located on the passenger side does not appear to function for locking the vehicle, indicating the necessity of a remote for locking.

2. Overcoming Key Programming Challenges with Precoded Chips
   Precoded ID46 transponders often present difficulties in programming due to unique encryption or vehicle-specific requirements. A 2011 Smart Car Fortwo job demonstrated this, where initial programming attempts with original ID46 and cloned XT27 transponders failed. To resolve the issue, we ordered specialized chips from Emirates, including both 433MHz and 315MHz options.

   • Programming Steps: Multiple transponders were tried, and two chips were successfully programmed, but remote functionality was still problematic.
   • Solution: The customer opted to continue with a cloned chip for manual unlocking, as further remote solutions were not pursued.
   • Considerations: Ordering multiple frequency options may be necessary, as some vehicles have specific compatibility requirements.

Key Programming Tools and Techniques

1. Smart Pro – The Locksmith’s Go-To for Smart Cars
   The Smart Pro remains a reliable tool for Smart Car key programming. It allows for cloning of transponders and key programming via OBD, although remote programming can be more challenging. When programming new keys for the Fortwo, for example, we successfully used the Smart Pro to code a cloned chip with the KDiy smart 315 remote programmer.

2. Cloning and Alternative Programming Methods
   In cases where standard programming fails, cloning provides an alternative. By copying the data from a functional key, a new transponder can be created. For the 2011 Fortwo, cloning to an XT27 transponder was used after multiple programming attempts with precoded chips failed.

3. Handling Remote Key Functionality
   Smart Car remotes are notorious for their programming complexities. The Fortwo requires a compatible remote for full locking functionality, as manual locking via the emergency door lock may not be sufficient. It is crucial to confirm the correct frequency (either 433MHz or 315MHz) before programming.

Troubleshooting Common Smart Car Key Issues

1. Programming Failures with ID46 Transponders
   The ID46 chip is widely used in Smart Car key systems but can present programming difficulties. Issues can arise from encrypted signals or mismatched frequencies. In these cases, cloning tools such as VVDI Key Tool Max and KDiy remote programmers can be used to bypass direct programming challenges.

2. Remote Synchronization Problems
   Remote key functionality is often required for locking and unlocking, particularly with Smart Cars where manual door locks may be limited. If the remote does not synchronize with the vehicle, consider testing different frequency options or using EEPROM programming techniques to access the vehicle’s control module directly.

3. Challenges with Emergency Lock Functionality
   Some Smart Cars, like the 2011 Fortwo, may have an emergency door lock that does not fully lock the vehicle. This can pose a security risk if the remote fails. It’s important to verify that the remote is correctly coded and functional to avoid reliance on manual locking.

Best Practices for Smart Car Key Programming

1. Verify Key Frequency Compatibility
   Always check whether the vehicle requires a 433MHz or 315MHz frequency remote. Incorrect frequencies can cause programming failures, even if the transponder appears to be correctly coded.

2. Use Cloning as a Backup Approach
   When direct programming fails, cloning the existing transponder data can provide a quick solution. Ensure that the cloned key is tested for both ignition and remote functionality, where applicable.

3. Confirm Remote Locking Capabilities Post-Programming
   After programming or cloning, always verify that the remote locks and unlocks the car effectively. In some cases, further steps may be required to sync the remote with the vehicle’s system.
