Solution to program a key of Renault scenic 3

Is there another solution, to program a key of scenic 3, other than with access to the dealer? a tool able to do this, I also bought a blank card because I have a card dropped me "no longer detected"  So before losing the last one.

Suggestion:
There is Renolink, soft develop by Gabi, to see if it supports Megan and scenic 3 and also Renault ecu tool (RET), for RET to count about 800 £ uros not easy to make profitable for a particular, Renolink is more affordable to see the price with its designer.
To know that the new vehicles whose Clio 4 second-generation must Renault net because they are secure for learning.
For all new vehicles clip will not help if not Renault.net
It must be added that a card must be preprogrammed by the seller or by means of a ZED BULL or other programming tool.

Genuine user's experience:
I programmed a few days ago a new key for my scenic 2 pH 2 using a Renolink interface 1.49, from China. You should first get the right pin then enter in after-sale mode. Program all the keys and then validate.
You have to go to Misc/Key/ choose Uch scenic 2, then connect. If all is OK you can see and copy the pin.
Then return to the main soft and find the Uch ecu (uch_84_j84...) then go to after-sale. Copy the pin in "code apv" and push "armer mode apres vente". You can now program your keys.
For me it worked.
