I needed a replacement key for my Smart Car recently so I went to Smart upgrades and had it done. The new key, unlike the previous one, only had two buttons. It was missing the remote ‘boot-opening button’.
When I asked why I was told the model I had didn’t offer that feature. Yet my existing key has the button and it works. Turns out all Smart models are built with the remote control receiver, you just don’t get the key. The functionality is deliberately turned down purely to allow a level of product differentiation!
