Spare keys

Only one car key left? Plan a useful spare

A spare is most useful when it is compatible, complete and available when the everyday key is not. Here is what to discuss before arranging one.

What you need to know

  • Confirm that your everyday key works reliably.
  • Ask which functions the quoted spare will provide.
  • Keep the spare separately once the work is complete.

Start with the key you already use

Confirm whether the current key opens the doors, operates the remote and starts the engine reliably. Say if any function is intermittent. A spare-key request based on a healthy working key is different from trying to reproduce a key that already has a fault. Include the registration and a photograph if it helps identify the key type.

Decide what the second key needs to do

A key can have a mechanical blade, a transponder, remote buttons or proximity functions. Ask which compatible options are available and what each quote includes. The cheapest item described online as a “car key” may be a casing or blank rather than a ready-to-use replacement. A familiar shape is not enough to establish that the electronics are appropriate for your vehicle.

Ask before buying parts yourself

If you already have a replacement key from another supplier, share its details before the appointment. Say whether it is new or used and whether it has ever been programmed. Sebastian can then assess whether it is suitable rather than discovering a mismatch at the vehicle. Do not assume that every purchased key can be programmed simply because the blade fits.

Choose a suitable time and location

When the existing key works, you can plan the visit at an agreed home, work or parking location. Check that the vehicle and the keys requested for the procedure will be available. Tell Sebastian about gate access or managed parking before the time is confirmed. A flexible quote helps establish compatibility and cost before you commit to the arrangement.

Make the spare useful afterwards

Keep the spare separately from the everyday key and make sure authorised drivers know how to access it when needed. At handover, understand which functions it provides and ask about any remaining questions. If the only key disappears before the planned work, tell Sebastian immediately: the request has changed to all keys lost and may need a different plan. You can organise the visit by WhatsApp or telephone, using online booking only if it is offered and convenient.
