Subject: Cardlock Canada locations
Thank you for contacting Pilot Flying J Guest Services!
Card Locks are convenient unmanned locations with commercial lanes with some limited amenities.
You are able to use your RV Plus Charge Card, but you will not be able to use your loyalty points card.
You may use other credit cards, as long as they are ones accepted by the location.(It should show the type of cards accepted on the pump)
I hope this information has answered your questions and if you need further assistance, please contact us by email or calling 1-877-866-7378.
