Baby, when you're far away from me
 call me up on my cell phone
 I feel your vibrations come through the phone
 right into my heart
 If you wanna be my caller I'm
 pleased to be your receiver
 I know when my favorite-melody sounds
 that you're on the line
 
 Suddenly, suddenly
 Something happened to me
 suddenly you appear with the key to my heart
 Suddenly, suddenly
 Something came over me and
 you set me free - You're
 The key to my heart
 The key to my heart 
 
Until you are here with me again
 I don't mind being your call girl
 If you are alone, just lay yourself down
 in my answering-maschine
 You know you can keep me satisfied
 just by being "under cover"
 there's no one I rather want to have
 inside my phone
 
 Suddenly, suddenly
 Something happened to me
 suddenly you appear with the key to my heart
 Suddenly, suddenly
 Something came over me and
 you set me free - You're
 The key to my heart
 The key to my heart 
 
Suddenly, suddenly
 This is pure extacy
 suddenly you appear with the key to my heart
 Suddenly, suddenly
 I will never be lonely
 you are my only
 The key to my heart
 The key to my heart 
 
You're all that I ever
 and it's now or never
 You're forever the only one...
 
 Suddenly, suddenly
 Something happened to me
 suddenly you appear with the key to my heart
 Suddenly, suddenly
 Something came over me and
 you set me free - You're
 The key to my heart
 The key to my heart
