EMTEK front door lock.
Tom K.

During a painting project last January I decided to replace my old EMTEK front door lock assembly that was not working well. I figured my best shot at success was Rex Key & Security in Berkeley, CA. I had never been there before. I think they must have everything lock related and the most knowledge people I have ever met to help. They found a lock assembly for me and had it shipped. Unfortunately it was not an exact replacement and to acquire an exact replacement was more $$$. Why this review? Perhaps when you have a need for a speciality part you will think of these people or just go there and see their shop. It is amazing. If your business will require extra time as my visit did they may even let you park in their lot.

Very dangerous driving - stay away! I had a terrible experience with a driver from this company. They cut me off aggressively on the road, putting my safety and others at serious risk. There was no signal, no regard for traffic rules, and it was completely reckless behavior. If this is how their employees or contractors act on the road, I'd be very concerned about the professionalism and responsibility of the company overall. I would never trust them with any kind of service. Safety should be a priority -- clearly, it isn't here.

Over a million keys....

After putting 40 minutes on the parking meter, I was prepared to wait. This funky nightstand key took me from Albany and Kensington to Berkeley. I walked into this place, and a wall of keys greeted me with their shiny teeth. I made contact with one clerk, shared my challenge, and unveiled the key that every duplicate machine rejected. The man took one look at my key, twisting it between his fingers. Less than thirty seconds later he hands me my original key and three duplicates. I heard no machines. This guy had perfect pitch...just in terms of keys. I played one key, so to speak and he knew that exact key. For those of you with running stopwatches, I was in and out with in 3 minutes tops! These guys, pleasant and professional, here at Rex Key and Security have the keys to success. Lock in with these guys if you need duplicate keys. Teacher-approved.

Cylinder was slightly twisted

Yesterday we were at my brother in law's home on Greenwood. He has had a stroke and hasn't been…read morethere for quite sometime and we were there to see what needed to be done. As you can imagine it was an emotional time. Upon trying to enter, we found the lock on the back door wasn't working and we weren't able to enter. Fearing that because we weren't the owners, a locksmith would not help us, we contacted the realtor who was able to provide your company with the necessary documentation. Your technician, Edgar, was dispatched and arrived quickly. He was able to diagnose the problem, repair the lock and open the door. I'm sure that to you, that is his job description but to us, he was a life saver. We had driven 2 1/2 hours to get there. The purpose of this long email is to commend Edgar for his expertise and kindness. He worked quickly all the while explaining the problem. Once he had repaired the lock, he spent the time to go over the fine points of the locking mechanism. Above and beyond repairing the lock, Edgar's kindness and positive attitude made this difficult day so much better. Thank you.

Warning: Lockology Locksmith (Bay Area) lacks T1N SKREEM programming capability / predatory…read morepractices I apparently need to post a warning to T1N owners . My 2006 Sprinter threw the"Start Error" code after i had a clueless locksmith (#1) clone a spare key. Knowing it was a " rolling-code mismatch between the ECU and the SKREEM/WSP module" , I called Lockology (locksmith #2) and explicitly stated that I needed on-site module resynchronization/EEPROM pairing. They sent out a tech named Ori who clearly didn't have the diagnostic tooling or the knowledge required for "offline variant coding" on the older K-line Mercedes network. Instead of admitting he couldn't do the job, he just cut a mechanical key , acknowledged my start error didn't go away , threatened to CALL THE COPS if the full quote to fix my Start Error wasn't paid (originally 560$..) , played the victim crying that he had been here longer than he planned only to be compassionate offering a 10% discount .$450 (Invoice #26411) .. You talk about a 4' tall snake. Big surprise, the Start Error is still flashing, and Sprinter still completely immobilized. Dispatch and tech took advantage of the situation knowing full well a physical key cut wouldn't resolve a hard immobilizer code loop. Save your money . What these guys offer together with 25 cents might get you a cup of coffee.
