If the key fob or electronic key is not working, getting into your vehicle will require a mechanical key. Most Vauxhall and Opel models use a simple flip or fold out key fob. Push the button in the corner of the front of the fob (arrow, right) and the mechanical key will unfold.
In most cases, a key hole is visible at the back of the driver’s door handle. If this is the case, insert the mechanical key and turn, and you’re in. Many key holes are hidden…
To replace the cap, insert it with the lower side in the recesses. Then rotate it upwards and push it until the cap engages at the upper side.
Remember, getting in the car is most important. If you have difficulty replacing the cap, don’t. Let your dealer do it when you get a new battery for your Key FOB!
