truck lock will not open
 

i have tried opening the trunk on my 84 300sd.
tried and tried. can hear i believe metal moving inside the lock?
help! - francis

mr forced induction - thank you for coming to my aid but could you please elaborate on cycling the lock and cycling the driver's door? simultaneously? - francis

thank you again mr forced induction. i will have to order a second key to perform what you advised. - francis

if i were to turn the key in the trunk lock to the open position the key is 'locked' and will remain in the lock, the second key i will need to cycle the driver's lock.
am i following your instructions correctly?

assuming i read and understood you correctly and the vacuum is still not cooperating to open the trunk lock it appears i will have to remove the back seat and manually coax the lock to work.
any suggestions? thanks again mr forced induction.

for any mercedes owner to purchase a spare key the dealer will want your car registration and driver's license.
i might receive my key from fort worth , texas in one day!
about $23.
