Ok, Now everything is getting so expensive, here to share some knowledge to help members to save some $$, No point going to get 3rd party to do a simply DIY job like this.
Hope this is useful and i believe you will need this is time to come.
Change your Ikey Battery yourself, buy the CR2025 at any $2 shops cheap cheap. Don't goto those camera shop or duplicate key shop.
1 - you need a test pen to ply open the Ikey cover
2 - slowly place the tip of the testpen into the slot & twist open abit
3 - slowly pull open using your fingers, pull open from the side till it fully open
4 - Tata, thats easy.
Happy saving
