If the 'Send eKey' button on the app is not working and returning an error message, try the following:
Correct details entered in the Mobile and Email fields
To send an eKey to someone, you have to make sure their email and mobile number is entered perfectly and without duplicates. This includes the '0' after the country code for the mobile number if applicable.
If the user has created an account using the mobile number +610412345678 and you've sent the eKey to +61412345678, they will not receive the eKey.
Duplicate eKey under the same email or mobile
For example, if you've already sent a key to an email or mobile and you've attempted to send another one to the same email or mobile, it will not work.
Go to the 'eKeys' list and remove all the eKeys for that lock and potential duplicates and try again.
