If "B173D" was a typo and you are looking for a review on a standard Peugeot model used for "work" (commercial/professional use), here is an assessment of the modern Peugeot work lineup:

Demystifying Fault Code B173D in Peugeot Vehicles: Symptoms, Causes, and Solutions

Remember: a single B173D code rarely means the key or BSI itself is faulty. With patience and methodical testing, you can get your Peugeot back to full health and enjoy many more miles of trouble‑free driving.

Every keyless Peugeot features an emergency transponder slot or a designated spot on the steering column where the key can be held. Placed here, the vehicle reads the chip using passive electromagnetic induction. If the car starts using this method, your issue lies strictly within the remote's battery or the vehicle's long-range antenna network. Step 2: Replace the Key Fob Battery b173d peugeot work

The BSI module receives power through multiple fuses, some of which are located directly on the BSI board. A inside the BSI has been reported as a direct cause for B173D and related immobilizer faults in several Peugeot Dispatch/Expert models. Replacing the fuse restored normal operation.

Turn off all electronics, close the doors (do not lock), and remove the key.

: Turn the ignition to the "ON" position (without starting) and leave it for 2 minutes to allow the key and BSI to re-establish communication. Common Causes for B173D If "B173D" was a typo and you are

These symptoms can be confusing, but they often point away from the key itself and toward a power delivery issue affecting the BSI.

By following the systematic diagnostic workflow outlined in this guide—starting with the battery and moving through fuse inspection, BSI reset, earth checks, and key synchronisation—most owners can clear the B173D code without expensive component replacements. Even if professional help is required, understanding the code’s meaning and common causes will enable you to discuss the problem knowledgeably with your repair shop, potentially saving both time and money.

The most common point of failure lies within the handheld key fob itself. Over time, the internal CR2032 or CR2016 battery weakens, decreasing the transponder signal's amplitude until the reader can no longer capture it. Alternatively, dropping the key fob can crack the internal PCB trace or dislodge the delicate surface-mounted transponder chip. 2. Faulty Ignition Switch Reader Coil or Antenna
