Smart Car Immobiliser & Key Systems
Since the launch of the Smart Fortwo in 1998, Smart vehicles have been fitted with immobiliser systems as standard.
Earlier Smart Fortwo models used a unique remote-controlled immobiliser system where:
- The unlock button deactivates the immobiliser
- The lock button activates the immobiliser
This means that on many pre-2006 Smart Fortwo models, if the remote fob battery fails, the vehicle may not start at all.
Because of this, having a spare Smart key is strongly recommended.
Unlike many manufacturers that relied purely on transponder chips, these earlier Smart systems linked the immobiliser directly to the remote fob operation itself.
Smart Transponder Key Systems
From around 2006 onwards, Smart vehicles moved to more advanced transponder-based immobiliser systems using Philips type 46 transponder chips.
In these later systems:
- The immobiliser is controlled by the transponder chip
- The remote central locking operates separately
- Replacement keys require specialist programming equipment
We use advanced Smart and Mercedes-compatible programming equipment to supply and program replacement Smart keys and remote fobs quickly at your location.
