Hello,
based on my experience with this device, this is only possible
if you followed rules by Meticulus...
Using his recovery you should have created a backup
through which return to rooted stock.
If you don't have that backup this is not possible anymore...
Cheers

Sadly i dont have any backup but i have the bootloader unlock code. If i do a full ota can i unlock my bootloader with the same code?

you have to go back to stock first.

If it's still locked, do you mind keeping it that way for just a little bit? It's possible we can figure out how to re-lock if we can get a bootloader dump. It's also possible that unlocking your bootloader will report to ASUS that it's been unlocked and it will void the warranty even if we can figure out how to lock it back up.
Maybe try this tool: https://play.google.com/store/apps/details?id=ma.wanam.partitions
And then report to this thread: http://forum.xda-developers.com/zenfone-2-laser/general/ze600kl-official-bootloader-unlock-t3273263

You'll need the Stock N firmware to do that. Wait a few days/weeks and someone might upload it and post it here.
After that, you can use fastboot to flash the stock image, relocking BL in process.

Why would you do that? Warranty is gone anyway - when you have requested the bootloader unlock code from Moto, they keep that request on file.

I no longer need my bootloader to be unlocked so relocking is the best option for me

Don't relock bootloader with MM ROM.
(if you already have N firmware, right now)
After flashing MM, you will receive OTA for N, and it will brick your device.
Do it with latest N september patch (available in guide section)

You can, but you need to remember that "don't take OTA in future, never tap update notification"
Also if you sell or give your phone to someone else, give them latest N.

Yes, fastboot commands are same.
hi! i know this is something irrelevant but since this is related to bootloader unlocking,i wanted to question that if i wanted to relock my bootloader which was on the sept 01 patch when unlocked;would i have to flash the same build from the fastboot again to relock it?and will it be safe to install ota updates after relocking the bootloader and reverting to the stock rom?

Only for taking OTA, locked bootloader is not necessary, you can take OTA with unlocked bootloader too.
things to take care of,
don't flash older firmwares than you have at the moment,
As you have september patch, flash september (while relocking too), don't downgrade.
If you downgrade, then don't take OTA. Warned..

My bad!
GPT and bootloader won't get flashed if you downgrade, it will fail, you can't flash older versions.
I don't know if it's possible to lock without flashing them, You can try flashing without GPT and Bootloader.
Just a suggestion! You don't need to flash the firmware again, if you are already on it. For eg, If you are already on Sept patch and want to relock, you don't need to flash the ROM again to relock it. Just use the fastboot commands.
I would recommend to leave it unlocked, because if anything went wrong with your device, atleast you will be able to save the data of internal memory atleast!
