Should I wear maruti pendant or use keychain?

I'm having sadesati hence I was suggested to wear Maruti pendant or Use keychain with photo of maruti on it. Should I go ahead with it? If yes, any specific suggestions? Is it recommended to wear panchmukhi maruti ( as reference photo) or maruti in sitting position? https://preview.redd.it/az1fjux4duhe1.jpg?width=415&format=pjpg&auto=webp&s=0305c955b0342637afe8d8f4a6db8054c5b28fe6
