Terry’s Locksmiths and the 1998-2006 Daihatsu Sirion

1. Key and IMMO System Challenges

The Daihatsu Sirion, particularly the models from 1998 to 2006, presents a unique set of challenges for locksmiths due to its key and immobilizer (IMMO) systems. The vehicle typically uses a TOY38R non-transponder key for early models and a TOYO-20D.P transponder key for later ones. The IMMO box is often located behind the glove box, which can complicate access and repair work.

2. Job History Analysis

Job 56643: Locksmith Kent worked on a 2000 Daihatsu Sirion where all keys were lost. The solution involved using an aftermarket turn-key non-transponder key, specifically the TOYO-20D.P, a Toyota Daihatsu N-R Transponder Key. The job required handling the TOY41R and TOY38R keys, highlighting our capability to manage both older non-transponder keys and newer transponder systems.

Job 58312: Another notable job involved a 2005 Daihatsu Sirion with all keys lost. For this job, locksmith Kent utilized an aftermarket turn-key non-remote solution. The tools used included the Orange and MIT-8D.P1 Mitsubishi N-R Transponder Key, showcasing our expertise in working with the 4D67 Daihatsu chip and the specific requirements for key programming and IMMO system synchronization.

Technical Insights:

  • TOY38R Keyway: For early models of the Sirion, the TOY38R non-transponder key is used. Key codes can be retrieved from the door lock, and locating the reader coil is essential for proper key function.

  • IMMO System Location: For both early and later models, the IMMO box is typically located behind the glove box. This positioning requires skillful disassembly and handling to access and repair the IMMO system effectively.

  • Chip Types and Programming: The 2005 model utilizes a 4D67 Daihatsu chip, which requires precise programming. Our use of advanced tools like Keydiy and Orange ensures accurate key programming and system integration.
