The Key's Teeth Matched the Bones in My Spine

By then, the key had already been turned once.

I worked evenings at a locksmith shop owned by Edna Vale, who had been cutting keys since before machines did most of the work. She taught me how to impression a lock by feel, how to recognize a failed pin from the sound, and how to refuse customers who could not prove a lock belonged to them.

She also kept three rules taped inside the key cabinet.

NEVER COPY A KEY THAT IS WARMER THAN YOUR HAND.

NEVER CUT A BLANK THAT HAS NO SHOULDER.

IF THE MACHINE ASKS WHO AUTHORIZED THE COPY, DO NOT ANSWER.

I thought the rules were jokes left for apprentices.

The customer arrived ten minutes before closing during a hard rain. He wore a brown suit darkened at the shoulders, but the floor stayed dry beneath him. His skin smelled like hot pennies and the stale air inside a locked house.

He placed a black key on the counter.

It had a bow and a long blade but no teeth, grooves, or stop. The metal was smooth as bone. When I picked it up, it was warmer than my palm. A pulse moved through it slowly.

“I need two copies,” he said.

“What does it open?”

“Not what. Who.”

I set the key down. Edna was making a service call across town, and I wanted the stranger gone before I locked up. I should have refused him. Instead, I chose two brass blanks and clamped the black key into the duplicator.

The machine would not start. Its digital display, which normally showed cut depth, produced a sentence.

WHO AUTHORIZED THE COPY?

The customer leaned closer. “You do, don't you?”

I pressed the green button.

“Yes.”

The motor screamed.

The cutting wheel never touched the original. It swung toward me instead, tracking my body as I stumbled backward. The two blanks began moving beneath the blade by themselves. Brass shavings curled onto the tray, wet and red at their edges. With every notch, pain clicked down my back.

When the machine stopped, twenty-three cuts marked each key.

The customer took one. The other had fused to the clamp. He smiled as if I had handed him the deed to a house.

“You kept the inside copy,” he said. “That's polite.”

He left without paying.

I locked the front door. Every cylinder in the shop turned at once. Deadbolts slid open, then closed, in a ripple from the entrance to the storeroom. Keys hanging on the wall rotated on their hooks until all their teeth pointed toward me.

From inside the locks came a whisper in my own voice.

“Let me in.”

I called Edna. When I described the black key, she told me not to move and hung up.

The fused copy was still hot. I wrapped it in a towel and tried to pry it from the machine. The moment I touched the bow, my legs stopped working. I remained standing but could not move, as though a bolt had shot through every joint.

Behind me, something inserted a key into the base of my neck.

There was no hand, no pressure—only metal entering a keyhole I did not have. The first turn moved seven vertebrae. I heard them click in sequence. My head fell forward. A seam opened down my back, not through skin but through the space my body occupied. Cold hallway air poured out of me.

I smelled another house: boiled cabbage, dust, old wallpaper.

Footsteps approached from very far inside.

Edna shattered the front window with a tire iron. The paralysis broke when she dragged me across the counter. The key turning behind my neck vanished, but the seam remained as a line of bruises along my spine.

She unplugged the duplicator and covered it with a welding blanket. Then she pulled the fused copy free using insulated tongs. It came away easily for her.

“You told it yes,” she said.

I asked what the customer was.

“A tenant.”

Edna showed me a ledger stored beneath a false floor panel. Locksmiths had recorded similar keys for more than a century. They appeared when a person had worn one body too long. The original key fit the body's inner lock. Years of turning wore its teeth smooth. To move, the tenant needed a locksmith to authorize a fresh pattern.

The cutting machine had not copied his key.

It had measured me.

One duplicate could open my body from outside. The other could lock or release whatever entered. The stranger carried the first. The fused key was the only thing that might keep him out.

“Why twenty-three cuts?” I asked.

Edna looked at my back.

“Because locks need pins.”

We closed the shop and drove to her house. I held the inside key in a vise-grip so I would not touch the metal. Halfway there, every door in the van unlocked. The radio changed stations without power. On each frequency, the stranger spoke in the voice of someone I trusted. My mother asked me to pull over. Edna's dead husband begged her to open the passenger door. A child I had not heard since elementary school whispered my full name.

At a red light, the customer stood beneath a streetlamp.

He raised his key.

My spine unlocked.

The van's seat dropped away. I fell backward into a narrow corridor papered with memories. Doors lined both sides. Behind one, I heard my parents arguing when I was six. Behind another, my first apartment faucet dripped. The corridor had existed inside me all my life, every forgotten room preserved behind bone.

The customer walked toward me from its far end. His brown suit hung loose now. Behind him, his old body stood at the intersection, empty and folded inward like a coat on a hook.

“You have plenty of space,” he said.

He passed through doors as he approached, trying on my memories. His face became younger with each one. Mine. At twelve. At twenty. Yesterday morning.

Outside the corridor, Edna shouted for me to hold still. The inside key pressed against my lower back. I felt its teeth align with every vertebra.

“If I turn this,” she said, “one of you stays in there.”

The customer ran.

I told her to turn it.

The corridor folded shut around us. He reached me as the last door slammed. His hands entered my chest. His mouth covered mine from the inside. Then the key snapped.

I woke on the roadside. The stranger's empty body had collapsed beneath the streetlamp. Police found no identification, fingerprints, or teeth. Edna drove me to the hospital, where the X-ray showed a bright brass fragment lodged between my lowest vertebrae. Surgeons said removing it would paralyze me.

Edna believes the lock closed before the tenant crossed. She says the broken key trapped him in the corridor, where he cannot control me.

Most days, I believe her.

I returned to work last week. Customers still need spare house keys, and ordinary locks calm me. But sometimes a key comes off the machine warm. Sometimes it smells like hot pennies and rooms I have never entered.

Yesterday, a woman asked for three copies of her apartment key. As I reached for the blanks, my mouth answered before I could stop it.

“Two will be enough.”

Her key cutter started by itself.

Twenty-three locks clicked inside my back.

From the corridor behind my ribs, the customer whispered, “One for her. One for us.”
