Premium locks are generally poorly made and do not fit well. I spoke to both Noble Locks and Dell before placing an order for the Noble Locks TZ04T Wedge Lock and specifically asking which Noble Lock model I need for the new Alienware 17"R4. Both companies advised me Looking to buy the Noble Locks TZ04T Wedge Lock When I received the lock the Noble Locks TZ04T wedge lock didn't fit properly and if you try to lock it with a slight pull the lock immediately opens with their infamous call - The center couldn't accepting that the lock didn't fit and insisting the TZ04T lock would suffice, although I repeatedly told Dell I had my hands on the same TZ04T lock and told them it didn't fit. Then I called Noble Locks again, this time someone told me that the TZ04T wedge lock works on all Alienware devices BUT there have been reports of problems with this lock on Alienware 17"R4. Your decision; A representative from Noble Locks told me to "put pressure and pick the lock in the hole". YOU LAUGH! GET A $3,000 Laptop Lock! Noble Locks should be ashamed, as should Dell for switching to Noble Locks! Dell must return to Kensington Castles. Save money and time. If you have an Alienware 17"R4, do not buy this lock. TZ04T DOES NOT WORK! Update: August 10, 2017 I just received my Kensington CLICKSAFE lock for CUSTOM SLOT and the Kensington lock fits perfectly! If you have a Alienware 17 have " R4 DO NOT SPEND your time on Noble, buy a Kensington Lock K67974WW.
