What to do if…
a car-share vehicle will not unlock even though your booking is active

Short answer

Stay with the vehicle (in a safe spot), confirm you’re at the correct car and your booking has actually started, then call the car-share provider’s support line while you are still next to the vehicle.

Do not do these things

  • Don’t force the door, window, or reader panel (you could be held responsible for damage).
  • Don’t keep repeatedly pressing unlock for several minutes without changing anything (it can waste time and increase stress).
  • Don’t walk away assuming it will fix itself if you’re close to the start of your booking (support often needs you beside the vehicle to troubleshoot).
  • Don’t accept “help” from strangers who want you to share login codes or let them use your phone.
  • Don’t try improvised “solutions” (tampering, towing, pushing) unless instructed by the provider or an authorised official.

What to do now

  1. Move to a calmer, safer pause point. Step a few metres away from traffic/driveways, keep your belongings with you, and take 3 slow breaths so you don’t rush into damaging the car or losing your booking.
  2. Confirm you’re at the right vehicle and the booking has actually started. Match the registration/number plate (and any bay/spot ID) to the app. If you’re early by even a few minutes, many services won’t enable “start/unlock” until the exact start time.
  3. Check the most common phone/app blockers (only what applies to your operator).
    • Make sure your phone has enough battery to stay on a call.
    • If your operator uses phone-unlock, confirm the app has the permissions it needs (commonly Bluetooth and sometimes Location Services).
    • If you have no data signal (e.g., underground), step briefly to where you can load/refresh the booking screen, then return to stand right next to the car before trying unlock again.
  4. Try one clean unlock attempt (then stop and escalate).
    • Fully close the app, reopen it, go to your active booking, and press Unlock/Start rental once.
    • If your service uses a smartcard, try that method once (hold it to the reader long enough to register, if applicable).
  5. Call the provider’s support/helpline while you are still with the vehicle. Tell them:
    • you have an active booking (start time/end time),
    • the vehicle registration,
    • exact location/bay,
    • what the app shows (greyed-out button, spinning, error message),
    • what you already tried. Ask them to note the access failure on your booking and to end/restart/reassign it if needed so you’re not charged for time you couldn’t use.
  6. If you’re stuck somewhere unsafe, prioritise personal safety. Move to a staffed/public place nearby (shop, station entrance, hotel lobby) and make the support call from there. If there is immediate danger to life, call 999.
  7. Preserve proof without getting pulled into billing right now. Screenshot the active booking page, the error, and the time; note the vehicle reg and location. This is for later if you need to dispute charges.

What can wait

  • You do not need to argue about fees, refunds, or compensation right now.
  • You do not need to write a detailed complaint while you’re stressed and stranded.
  • You do not need to do major troubleshooting (reinstalling the app, factory resets, changing phones) unless support tells you to.

Important reassurance

This is a common, fixable failure mode with app-based access. The most protective move is to slow down, confirm the basics (right car + start time), and get the provider to troubleshoot while you’re beside the vehicle.

Scope note

This is first-steps only: stabilise, verify, contact support, and document. Anything about longer-term account issues, charges, or membership status can be handled after you’re safe and no longer time-pressured.

Important note

This guide is general information, not legal advice. Car-share systems and procedures vary by operator and vehicle; follow the provider’s instructions and local safety guidance in the moment.
