What to do if…
you arrive at a station and the ticket gates will not accept your valid ticket or pass

Short answer

Don’t force the gate or follow someone through. Step aside, keep hold of your ticket/pass, and ask staff (or use a help point/intercom if available) to let you through and check your ticket.

Do not do these things

Don’t push the barrier open, jump it, or “tailgate” behind another passenger, even if you’re sure your ticket is valid.
Don’t throw away the ticket, delete the mobile ticket, or stop the screen from showing the QR/barcode.
Don’t get into a public argument at the gates or block the line; move to the side first.
Don’t buy another ticket in a panic unless it’s clear there’s no staff/help point available and you must travel—if you do, use an official channel and keep proof so you can sort it out later.

What to do now

Step out of the queue and keep your ticket/pass ready to show. Paper ticket, smartcard, Oyster/contactless card, or mobile barcode—don’t put it away.
Try one careful retry that avoids common “false rejects”:
- Use a different gate (a single reader can fail).
- For paper tickets, insert smoothly and wait for it to return (don’t pull it out early).
- For mobile barcodes, increase screen brightness and hold the barcode flat and still over the reader.
- For Oyster/contactless, tap only one card/device and keep other cards away to avoid “card clash”.
Go to the staffed gate (often the wide/accessible gate) and ask to be let through. Say: “This ticket/pass is valid but the barrier won’t accept it—can you check and let me through?”
If no staff are visible, look for a help point/intercom near the gateline (if available). Press it and explain you have a valid ticket/pass that won’t scan; ask for remote assistance or for someone to attend.
If you’re trying to EXIT and you’re stuck behind the gates, prioritise being released. Say: “I need to exit; my ticket/pass won’t open the barrier.” Let staff resolve the details once you’re out.
If it’s a TfL Oyster/contactless journey, keep it consistent. Use the same card/device to touch in and out, and don’t switch between phone/card. If you can’t get a successful touch out because of the gate, ask staff for help so your journey doesn’t stay incomplete.
Make a quick record for later (only if it stays calm). Note station, date/time, and (if visible) gate number and the message shown. If it’s clearly allowed and won’t inflame things, a quick photo can help—but notes are enough.

What can wait

You do not need to decide right now whether to complain, claim compensation, or “prove” you were right.
You do not need to buy a replacement ticket immediately if staff can verify you and open the gate.
You can deal with refunds, account corrections, or formal disputes after you’ve got through the barrier and you’re safe and calm.

Important reassurance

Ticket gates can reject valid tickets for unglamorous reasons: a faulty reader, a ticket type that needs manual checking, barcode brightness/glare, or “card clash” on contactless/Oyster. Needing staff to open a gate is common and doesn’t automatically mean you’ve done something wrong.

Scope note

This is first steps only—focused on getting you through the gates without making the situation worse. If this becomes a penalty fare dispute or happens repeatedly, you may need the operator/TfL or the retailer to investigate.

Important note

This is general information, not legal advice. Rules and gate behaviour vary by operator, station, and ticket type. If you feel unsafe or threatened, step away to a staffed area and ask for help.
