Programming Marks I-Que Lock

By admin | Comments Off on Programming Marks I-Que Lock


City Lock presents a simplified programming guide for the Marks I-Que Lite and I-Que Metro

The GGM is also known as the MASTER or Programming Code. Always change the Factory Default GGM during installation of a new lock

  • The GGM is also known as the MASTER or Programming Code. Always change the Factory Default GGM during installation of a new lock
  •  A User Code is generally a 6 digit code, and breaks down into two halves: the first three digits make up a “USER ID” and the remaining three digits constitute a “USER PIN”. When used to open the lock; it is combined into one string, and is called a User Code.
  •  The USER ID must differ from any already programmed into lock; ( For example; one User ID can be 612 and a new User ID can be 617, 834, 842 etc ). The remaining three digits of User Code is the Pin Code, and may be any digits person USER ID relates to wishes.
  1. Select an activity:
  1. To reprogram a lock using a common, shared single User code, perform steps one and two. Always DELETE the existing code first, and then ADD in new User Code. ( Both Step 1 and 2 )
  2. To add a user to a lock with multiple users, just ADD a new User Code ( Only Step 2 )

Program Lock:

        1. ( GGM )    #    01    *    ( User ID )    *   0   **     Delete a User

            Programming Code               First Half of User Code         


        2. ( GGM )    #    01    *    ( User ID )    *    ( User Group )   *   ( User Pin )    * *    Add User

            Programming Code                First Half of User Code             Ex: Group 10         Second Half of User Code


Some optional and useful function commands and features your Marks I-Que lock supports:

  • (GGM) # 12 * HHMM * *   Set Current Time
  • (GGM) # 13 * MMDDYY * *   Set Current Date
  • (GGM) # 02 * 13 * HHMM (Open Time) * HHMM (Close Time) * *   Basic schedule Open/Close times
  • (GGM) # 18 * 5 * *   Define Lock Open Time (Refers to time lock remains unlocked after entering user code, not the time lock unlocks during basic scheduling)
  • (GGM) # 32 * 0 * *   Pin Only Mode. This allows just the last half of user code to open door, for quicker entry. See full manual for longer pin codes, for added security.
  • (GGM) # 37 * 0 * *   Terminator off   (Terminator is the # entry at end of User code)  (Note: to enter programming mode with terminator off, you must first press the “#” key then enter your code.)
  • (GGM) # 16 * 16 * 0 * *   Clears All Users and Scheduling in Memory, in event you have lost your chart of users.

Your car keys, locks and remotes

By admin | Comments Off on Your car keys, locks and remotes

Today, let us look at Toyota  and Lexus keys. If you have any OTHER make, this technology still may apply to YOU!

I will examine what is called a “Remote Head Key”, or a “Remote Head Key Shell”. There are three elements we look at, though they may packaged in different ways; based on model and year:

Element 1  The Blade. The blade of a key is a precision instrument. Never use it as a screwdriver or can opener. This component is also a wear item. The blade has cuts that mate up to segments within the door and ignition lock to allow rotation when the correct key is in play.

Element 2: The chip. MANY cars since 1990, and MOST today, have RFID chip technology within the plastic head. Sometimes it is a glass or carbon wedge chip, molded or fixed in the plastic head, other times it is within the circuitry of the keyless entry module in the head of key, along with a replaceable battery. Many Toyota and Lexus models, particularly in the 1998-2002 range had a system that the dealer could only program spare keys if you had a working MASTER key. Locksmiths have had the means to reset this system, in the case of no master key present. This system was totally phased out of the last model by about 2006.

Element 3:  The Remote Head Key Shell. There is a large concern over separation of the blade from the plastic shell, as well as the cover separating that holds the remote capsule in the head on certain Toyota and Lexus keys. Locksmiths have long replaced broken shells, and transplanted the chips and remotes from the old shell into the new. There is one aspect car owners should be aware of; too much torque placed upon the head of the key, due to a lock issue, can cause expensive damage to the lock bolt housing on the steering column. This has been seen a number of times on Lexus vehicles. Worse than cost alone, some Lexus lock bolt housings are no longer produced at all. Particularly if you are using an “extra strong” remote/key shell, this is not meanign you should be using the device as a crowbar. I am sure it was not the intention of the makers nor sellers  to have people crank it extra hard to overcome a jammed lock. Any sign of a key not working smoothly, should be addressed before the issue becomes critical.

Element 4 ( The bonus element ) The REMOTE:

We notes that sometimes a remote will just stop working, especially after long term storage or after the vehicle has been serviced. City Lock can re-synch it, replace the battery etc.


Comments & Advise:

Toyota introduced two designs that use a key known as a ” TR43″ or “TR47”. Toyota launched the first variant in 1991. The lock design had specific, chronic issues. These issues were identified soon after product initial release, and we still service failing locks of this ilk. Toyota eventually offered a redesigned product, with a 5 year phase-in in which completed in 2007. The old design is called the 8 cut system, and the latter design is the 10 cut system.

The 8 cut system consisted of a lock design with up to 8 segment positions within each lock. Two of these positions contained split wafers. We believe this design was to thwart decoding of locks serupticiously; in an attempt to increase security. The problem with this design; the segments known as split wafers traveled in their respective slots erratically. The travel was not balanced. This caused the split segments to bind, and wear on both the key, the segment and the housing within its’ travel. Ultimately, clients would have an ignition that would not turn to start, or get stuck partially turned.

The 10 cut system abandoned the split wafers altogether, but added some features. This design used the same key stock as the old 8 cut system. There is no notable failure rate with this design. However; keys must be held tightly within tolerances. The slightest wear on keys will yield failure in one or more locks. It is advised that these keys be made by locksmiths well aware of the tight tolerances. Not all key machines, even CNC type ones, can produce a quality 10 Cut Toyota key.

When a driver has a problem with keys and locks, non-expert lock repairs and replacement are often misguided and unneeded. Conclusions pointing to the lock, without testing is a costly mistake. The failure is squarely a KEY problem just about every instance; so must be verified. This is totally unlike on the old 8 Cut, where the LOCKS were almost always in need of a servicing, along with replacement of worn keys.

We at City Lock can not emphasize enough; with any auto lock key, or remote; symptoms are not a diagnosis. Facts, and a logical sequence to repair in the most efficient, least wasteful manner must prevail. When we do lock rekey and repair, we keep the match-up of ignition and door, rather than throw additional keys that only fit a replaced lock. The extra care is what makes a car owner happy down the road.

In conclusion, have problems dealt with, early on. Do NOT throw away keys or remotes that are not working, or broken. Put all the bits and pieces in a bag, and bring it to City Lock and watch the magic.


City Lock is developing new job site security lock

By admin | Comments Off on City Lock is developing new job site security lock

City Lock is directly guiding the development of new padlocks. This project is to provide a new padlock for job-site tool chests. We are working with mechanical engineers and a US Based manufacturing plant with both our applications experience and customer input to develop products that are built to the needs of the market.

Help Us develop a new commercial padlock! Testers WANTED. We have a Beta run of locks to test.

Qualified clients of City Lock are invited to request a FREE padlock to put to the test. You must have job site tool chests such as Knaack, but we want all brands and variations.  These must be in daily use, not storage. Exposure to the elements and vandals is a plus. Tool cribs must be able to be brought to the City Lock showroom and service center in Boulder. We need the widest range of job site containers to test the fit. The factory label must be somewhere on the box. This information is needed so we can feed back to manufacturer of padlock how well the fit is for a particular product model and vintage; and attach any mods to the design we deem important. We will need feedback monthly. ( More frequentl input and suggestions are welcome )

The final engineering will be applied to keyed padlocks in standard, interchangeable core, high security and Bluetooth. Test padlocks are yours to keep. Final product will be available at a discount to all Beta-Testers.

City Lock is also interested in END-USER requests for other specialty padlocks to be developed. send your ideas through our contact page.

While we are adding new lines, existing clients who we have provided American Lock and Master PRo-Series locks should not be concerned. We will always support and have these locks available. We are adding a line that is compatible, so you can even mix and match and key alike between brands.
