The keys handed over at closing are not the only keys to the house. Over the years the previous owners gave copies to a housekeeper, a dog walker, two sets of neighbors, a contractor who never gave one back, and an adult child who moved out in 2019. None of that is on any document you signed. Rekeying in the first week is the cheapest security decision you will make on the property, and it is worth doing systematically rather than just handling the front door. Here is the checklist, in the order that matters.
Day one: the doors that are actually entrances
Walk the property and count every door that leads outside. Most buyers stop at two and there are usually five or six.
- Front door, deadbolt and handleset.
- Rear or patio door leading to the yard.
- The service door from the garage into the side yard, which is the one most often forgotten and frequently the weakest lock on the property.
- The door from the garage into the house, which many households leave unlocked entirely.
- The side gate, if it has a lock rather than a latch.
- Any casita, guest suite, or converted space with its own entry, common in Ahwatukee Foothills.
Count the cylinders rather than the doors, because a front entry with a handleset and a separate deadbolt is two. That number is what a rekey quote is based on.
Rekey or replace: how to decide
Rekeying changes the pins inside the existing cylinder so old keys stop working while the hardware stays on the door. It is substantially cheaper than replacing and it is the right answer for most doors.
Replace instead when the hardware is genuinely at the end of its life, when the grade is too low for the exposure, or when you want something the old lock cannot do. A hollow-slab garage service door with a Grade 3 knob and no deadbolt is worth upgrading rather than rekeying. A solid front entry with good hardware just needs new pins.
A technician doing lock rekeying will tell you which doors fall into which category during the walkthrough, and the honest answer is usually that most get rekeyed and one or two get replaced.
Get everything onto one key
This is the part people skip and later wish they had not. If the locks share a compatible keyway, the front door, back door, garage entry and side gate can all be matched to a single key in the same visit at little extra cost. You carry one key, the spare in the car opens everything, and there is no fumbling in the dark.
Where a lock cannot be matched because the keyway is different, you have a decision: replace that one cylinder to bring it into the set, or accept a second key. Replacing is usually worth it for an exterior door and rarely worth it for a shed.
Once the set exists, have two spares cut. House key duplication at the same visit costs very little and saves an after-hours call later.
The codes and credentials nobody transfers properly
Physical keys are only part of the handover. Work through the electronic access too, because these routinely carry over from the previous owner.
- Garage door opener codes. Clear all remotes from the opener memory and re-pair only your own, then reset the exterior keypad code.
- Any existing smart lock or keypad deadbolt. Do a full factory reset rather than just changing the primary code, since user codes and app access can persist.
- The community or gate code, if your Ahwatukee neighborhood has one. That belongs to the association, but confirm what the previous owner shared and with whom.
- Alarm system codes, including installer and duress codes.
- Any lockbox left on the property from the listing. Remove it, do not just change its code.
- Pool gate and equipment locks, which come with their own keys that rarely make it to closing.
The security gaps specific to these houses
Foothills homes share a few recurring weak points that have nothing to do with who has a key.
The sliding patio door is the most common. On many homes the factory latch is a convenience catch rather than a security device, and a secondary foot lock or a keyed pin through the frame closes the gap for very little money. This is standard patio door lock installation work.
The second is the side yard. A gate that separates the street from the back of the house is what stops someone working on a rear door unobserved. If it latches but does not lock, that is worth fixing in the first week.
The third is window hardware on the shaded side of the house, where original latches have usually lost tension. Window lock installation is quick and inexpensive relative to what it covers.
What the first week costs
Doing it all in one visit is cheaper than doing it piecemeal, because the dispatch is shared. The ranges below are planning figures for the Phoenix market.

Planning ranges for a new Ahwatukee home
| On-site residential project | Typical Phoenix-area range | What the quote covers |
|---|---|---|
| Rekey all exterior locks to one key | $110–$320 | Mobile dispatch, repinning compatible cylinders, and keys cut for the new set. |
| Rekey plus replacing one or two weak locks | $220–$550 | The above plus new hardware where the existing lock is not worth keeping. |
| Adding a keypad deadbolt on the main entry | $95–$220 labor | Install, strike check, and code setup. Hardware quoted separately. |
| Securing the patio slider | $75–$180 | Secondary lock or keyed pin fitted to the existing door. |
A realistic first-week order
- Day one: count the cylinders and book the rekey. Do not wait for the boxes to be unpacked.
- Day one: reset the garage opener memory and the exterior keypad code, which you can do yourself in ten minutes with the manual.
- Rekey visit: all exterior doors to one key, two spares cut, weak hardware replaced.
- Same visit: secure the patio slider and check the gate.
- Week one: factory reset any smart lock or alarm left on the property.
- Week one: decide whether a keypad on the door you actually use is worth it, and add it while a technician is already familiar with the house.
