Login to your Dashboard an find the key that you "lost". Merchant keys are located in the merchant settings are and sales channel keys in sales channel settings. On each place you will find a function which lets you roll the key. You can choose to roll immediately or issue a new key and let the old key be valid for another 12 hour so you have time deploying the new key. Choose wisely depending on your situation.
