The quick answer
There is no single completion time for every car. Ask separately about arrival, parts availability and the time needed for cutting, programming and checks. We confirm an estimate for the vehicle and current availability before agreeing the visit.
1. Separate the three waiting times
An arrival estimate describes when a technician expects to reach you. Parts lead time describes whether the correct key must be obtained first. Work time covers the assessment, cutting, programming and functional checks required for the job.
A claim about minutes spent making a key does not necessarily include the wait for attendance or a special-order part. Ask what an estimate includes, especially when arranging transport, work commitments or access to a car park.
- When can someone attend this postcode?
- Is the correct key available for my model?
- What work needs to happen at the vehicle?
- What could change the estimated completion time?
2. Explain the vehicle and starting point
Send the make, model, year and registration, and say whether a usable key remains. Explain whether the car is locked and whether the fault involves the remote, blade or starting function. Photographs of a damaged key or dashboard warning can help describe the problem.
Different key systems require different equipment and procedures. An all-keys-lost enquiry, a working-key spare and an intermittent ignition problem should not be given the same assumed time. Existing vehicle faults may need assessment before a key can be tested.
3. Prepare for the visit
Have all available keys ready and ask which identity and ownership documents are needed. Confirm where the vehicle will be, how the technician can reach it and whether there are gates, height limits or parking restrictions.
If you are beside a road, arrange assistance from a safe position and describe the location accurately. A key appointment does not itself confirm recovery or that roadside work can safely be carried out at that spot.
- Keep your phone available for appointment updates.
- Tell the team if the vehicle location changes.
- Mention any previous programming, key or battery work.
- Do not begin additional DIY work while waiting for assessment.
4. Compare realistic completion estimates
Neither a dealer nor a mobile locksmith is always quicker. Ask whether the key is in stock, whether the vehicle must attend a workshop and when it can actually be ready to use. Check support for your exact model before making travel arrangements.
Our mobile service accepts 24/7 enquiries across London, Surrey, Slough and Reading. Attendance depends on location, vehicle support and availability. Call for the current estimate; a website enquiry or message is not a confirmed booking.
Common questions
Can I get an emergency replacement today?
Call with your registration, full postcode and whether all keys are lost. The team must confirm vehicle support, key availability and a suitable appointment before same-day completion can be agreed.
Is programming always the longest part?
No. Obtaining the correct key, accessing the vehicle or investigating a fault may affect the overall time. Ask for a complete estimate rather than timing one step.
Are dealer replacements always slower?
No. The available parts and appointments for your exact vehicle determine the comparison. Obtain current estimates from each provider.
How can I avoid delays?
Supply accurate vehicle and location details, have available keys ready, confirm access arrangements and ask what documents are needed before the visit.
