GMC Locksmith in Metro Atlanta: Sierra, Yukon and Savana Keys at the Truck
Work trucks, family SUVs and cargo vans keyed where they are parked: a blade cut to the lock, a chip or fob programmed to the truck, a broken key drawn out of the cylinder, a whole yard of pickups handled in one trip. Lost every key? Read the model year to the dispatcher and the route is settled during that first conversation.

4Keys Locksmith is a mobile GMC locksmith serving Metro Atlanta, Georgia, NASTF VSP authorized, ALOA-trained, insured by The Hartford, and set up as 4Keys Locksmith LLC with the Georgia Secretary of State. Its technicians cut and program Sierra, Yukon, Terrain and Savana keys at the vehicle around the clock, with no shop involved, and the reason a mobile locksmith skips the tow is set out in do locksmiths come to you.
A GMC is a pickup on a job site, a van carrying a crew's tools or an SUV carrying a family, and a lost key takes the vehicle out of service until it is replaced. Everything a GMC can need is on the van: a spare while one key works, a key from nothing, Terrain flip keys and push-button fobs, ignition and cylinder work, extraction of snapped keys, module matching and lockouts, on old PASSLock trucks and on modern ones alike. The Sierra HD is covered the same as the half-ton, and a Denali with push-button start is handled like any other Yukon or Sierra of its year: the generation of the key decides the job, not the trim badge.
Before a technician is sent, the dispatcher gives you the price for the job; the published rates live on the 4Keys rate list. Dispatch speaks English and Spanish, and Spanish-speaking technicians are part of the team.
Sierra, Yukon, Terrain and Savana: which key each generation takes
Years as STRATTEC and Locksmith Ledger print them. Where a model year is missing, or a band reads 'from', the dispatcher confirms the key from your VIN on the call.
| GMC model | Years in the source | Key | Work available |
|---|---|---|---|
| Sierra | 1997-2003 | PASSLock blade with no chip; the security magnet sits in the ignition cylinder | Keys cut to the lock, cylinder replacement with the PASSLock relearn |
| Sierra / Sierra HD | 2007-2013 (HD to 2014) | Circle Plus transponder blade, stamped PK3 or "+" | Second key from a known one, keys from none, remote set-up |
| Sierra | From 2014 | GMC molded key with an encrypted chip; push-button trims carry a fob and a non-transponder emergency key | Spare, keys from none with the procedure matched to the year on the call, fob work |
| Yukon | 1996-2003 | PASSLock blade with no chip | Key cutting, cylinder work and relearn |
| Yukon | 2007-2014 | Circle Plus transponder blade | Spare, all keys lost, lockout |
| Yukon | From 2015 | GMC molded key with encrypted chip, or a fob plus emergency key on push-button trims | Copies, push-button fobs and keys from none, with the year checked when you call |
| Terrain | 2010-2017 | Side-mill transponder blade in a three- or four-button GMC flip key | Terrain flip keys copied or made new, snapped blades, keys from zero |
| Savana van | 2001-2004 | PASSLock blade with no chip | Van keys cut, cylinder relearn |
| Savana van | 2008-2014 | Circle Plus transponder blade | Van spares, all keys lost, several vans in one trip |
| Savana van | From 2015 | Coined key with no transponder, or molded-head Circle Plus side-mill key | Key identified from the VIN, cut and, where chipped, programmed |
Rows follow STRATTEC's two GM listings and Locksmith Ledger's PASSLock coverage. How those GM generations fit together is told on the Chevrolet locksmith page.
The molded Sierra and Yukon key: one key to add, three timed cycles to start over
Earlier Sierras ran the GM sequence every Chevy truck ran, from the PASSLock blade with no chip to the Circle Plus key stamped PK3, and that history is written up on the Chevrolet page. In 2014 the Sierra, and in 2015 the Yukon, moved to a GMC molded key that STRATTEC catalogs under its own part number, with an encrypted chip in the head and the remote on a separate fob, or with a push-button fob on trims that start with a button. The blade that rides inside or beside that fob is listed by STRATTEC as an emergency key with no transponder: it opens the door, and the fob is what the truck checks before it starts.
Adding a key to a 2014-2016 Sierra. STRATTEC prints GM's procedure for these trucks (OBP-10b) in two branches. With a key the truck recognizes, that key is switched to ON and off, the new key goes to ON within five seconds, and the truck accepts it; up to eight keys can be stored. With no recognized key and no dealer tool, the new key sits in ON for ten minutes until the security light goes out, is switched off, and the cycle runs three times, about thirty minutes in all. When it ends, every key the truck knew before has stopped working. The same text adds that Canadian owners are sent to a dealer.
Later GM encrypted keys want two. STRATTEC also prints a procedure for 2017-on GM high-security encrypted keys in which adding a key requires two recognized keys. With fewer, the thirty-minute cycle learns the first new key and drops the others, and a second key then learns with a plain ON cycle. The catalog does not attach a model list to that procedure, so the dispatcher matches your truck to the right branch from its VIN.
What that means for a GMC owner. A spare is simplest while a working key still exists, and on any truck that falls under the two-key rule, a second key is what keeps the next addition simple. A relearn from zero cancels every key the truck knew, so gather each key that should keep working: the ones at the truck can be added back in the same visit, the ones left elsewhere cannot. Where a model year needs dealer-level software, the technician reaches it at the truck under 4Keys' NASTF VSP authorization, running Techline Connect with SPS2, GM's dealer software, paid for by subscription, and pairing original (OEM) GMC fobs and keys with the truck; the dealer software question has its own page.
Sierra HD and the 2007 changeover. STRATTEC keeps the heavy-duty Sierra on the Circle Plus key one year longer than the half-ton, through 2014, which is why a 2014 Sierra HD and a 2014 Sierra 1500 can carry different keys. The 2008 transponder guide also lists a part of its own for the 2007-08 Sierra and Yukon. Read the stamp on the blade, or the VIN, to the dispatcher and the right blank goes on the van.
Savana and Terrain. The Savana followed the trucks through PASSLock and Circle Plus, then, from 2015, STRATTEC lists two different keys for it: a coined GM key with no transponder and a molded-head Circle Plus side-mill key, so the van's VIN decides which one is cut. The 2010-2017 Terrain uses a side-mill blade with a chip, folded into a three- or four-button GMC flip key. Push-button GM fobs and what a no-fob relearn does to the fobs you own are covered in depth on the Cadillac locksmith page.
Keying a yard of Sierras and Savanas without a dealer trip
How a company with several GM pickups or vans prepares, so the technician can work down the row. The general one-visit fleet process is on the Ford page and the fleet guide.
- 1
List each vehicle by VIN and model year
The year sorts every truck into its GM key generation: PASSLock blade, Circle Plus chip key, molded encrypted key or push-button fob. A Savana from 2015 on needs the VIN, since two different keys are listed for it.
- 2
Count the working keys on each one
A truck with a known key gets its spares added through the short sequence; one with none goes through the timed relearn, about thirty minutes on a 2014-2016 Sierra. Knowing the count lets the dispatcher plan the order and the time on site.
- 3
Collect every key you mean to keep
A relearn from zero cancels every key the truck knew, and only the keys at the truck can be added back during the visit. Pull keys back from drivers and the office beforehand, so nothing that still works gets dropped.
- 4
Decide how many keys each vehicle should carry
A 2014-2016 Sierra stores up to eight. One key on the truck and one in the office is the simplest way to avoid starting over next time.
- 5
Say which trucks must roll first
If two pickups have a crew waiting, tell the dispatcher on the call. The technician starts with those, then works through the spares and the trucks that can wait until the end of the visit.
- 6
Have the paperwork answer ready
The dispatcher tells you which papers the job needs while you are on the phone, and before arriving the technician may ring and ask for a snapshot of a key or the dash label. For several makes at once, see fleet van key programming and the Ford locksmith page.
Before the van leaves for your GMC: five answers that set the job
The model year, or the VIN from the dash label or the registration. How many keys still start the truck. What is stamped on the blade: PK3 or a plus sign means Circle Plus, a thick molded head means one of the 2014-on keys. Whether you already bought a fob, and its FCC ID and part number. And how the technician reaches the truck: a gate code, a yard contact, a deck level and row, a job-site cross street. With those, the dispatcher quotes the work on the call and loads the right blanks; a picture of the key, if the technician asks for one when phoning ahead, removes the last doubt.

GMC recalls that touch the key or the ignition: check the VIN first
The ignition lock actuator binding covered by 14V-827 includes the 2011-2012 Sierra and Yukon, and 15V-640 covers the 2014-2015 Sierra from narrow build dates; the dealer remedy replaces the ignition lock housing (the mechanism is explained on the Chevrolet page). On 2013 Savana vans from a narrow window, 13V-010 replaced the lock cylinder and both keys. Terrain model years including 2011 to 2013 are in 16V-502, a key that can come out of the ignition outside Park. Campaign 13V-001 had dealers inspect, and replace where needed, the steering column on 2013 full-size trucks, vans and the Escalade from narrow build dates. Open recall work is a dealer job; anything outside it is quoted on the phone.
From a driveway in Jonesboro to a truck yard in Conley
Vans are dispatched from Brookhaven across Metro Atlanta, and the dispatcher gives the arrival time on the call. South and west of the city that includes Conley, Jonesboro, Lithia Springs, Austell and Mableton. The truck is keyed where it is: a home driveway, a company yard, a job site, an apartment lot or a parking deck (give the level and row). A locked yard needs someone to open the gate or a code shared on the call; a job site needs the nearest cross street and the name of whoever is holding the truck.
The van that brings a GMC key also carries lock hardware for the house and the business. At home: lockouts, rekeying after a move, new locksets and deadbolts, keypad smart locks, described on residential locksmith service and Georgia residential locksmith. At a shop, warehouse or office: rekeys when people leave, master keys, card readers, panic hardware and storefront cylinders, on commercial locksmith service and Georgia commercial locksmith. One call can cover the truck and the building.
