Tenant-Turnover Rekey for Milwaukee Landlords: A Practical Playbook
Quick answer: Rekey between every tenant. Per-unit Milwaukee cost: $80-$150 for a 2-cylinder unit, $150-$250 for a 4-cylinder townhome. Bulk-scheduled (multiple units in one visit): $60-$120 per unit. The legal exposure of NOT rekeying is much higher than the cost. For high-turnover properties, smart locks pay back in 18-24 months.
The case for annual rekeys
Wisconsin landlord-tenant law (Wis. Stat. § 704) doesn't explicitly require rekeying between tenants. But case law has consistently held landlords liable when a former tenant returned with a copied key and committed theft, assault, or other harm against the new tenant. Most landlord insurance policies require reasonable security between tenants, and "reasonable" in courts has come to mean rekeying. The $80-$150 per unit cost is small compared to a single liability event.
Beyond legal exposure: the security-of-mind benefit to your incoming tenant is real. A move-in process that includes "we rekeyed every door for you" reduces tenant complaints and improves first-year retention.
Per-unit cost matrix
| Unit type | Cylinders | Per-unit cost (single visit) | Per-unit cost (bulk-scheduled) |
|---|---|---|---|
| Studio / 1-bedroom | 1-2 | $80-$120 | $60-$90 |
| 2-bedroom apartment | 2-3 | $100-$160 | $70-$120 |
| Townhome / duplex unit | 4-5 | $150-$250 | $110-$190 |
| Single-family rental | 5-6 | $180-$300 | $140-$240 |
Bulk pricing kicks in when we schedule multiple units in a single building visit. A 24-unit apartment building during a summer turnover wave: $1,800-$2,800 total ($75-$120 per unit), vs. $4,000-$5,500 if each unit is scheduled separately.
Master-key systems for landlords
If you don't have a master-key system, you should. The benefit: you (or your management company) hold a master key that opens every unit. Tenants hold their unit's individual key. Sub-masters can be issued to maintenance, cleaning, leasing agents, each with limited access.
Setting up a master-key system from scratch on an existing building: $400-$3,000+ depending on size. After setup, between-tenant rekeys cost $40-$80 per cylinder because we're working within the existing bitting schedule rather than designing a new one each time.
Smart locks for landlord rentals
Smart locks change the per-turnover cost equation. Initial install runs $200-$500 per unit + hardware. After that, you change tenant codes via the app, no service call needed for the rekey. For an annual-lease unit, that saves $80-$150 per turnover. Payback period: 2-3 turnover cycles.
Recommended smart locks for Milwaukee rental properties:
- Schlage Encode, Wi-Fi, no hub required, $280 retail. Best for landlord remote management.
- Yale Assure SL with Wi-Fi, Touchscreen, key override. $260 retail.
- Schlage BE375 (keypad-only, no Wi-Fi), Cheaper option ($120 retail) for landlords who don't need remote management. Tenant changes happen on-site.
Scheduling tactics that save money
- Schedule against your lease calendar. Most Milwaukee leases end June 30 or August 31. Bundle every turnover that month into 2-3 visits.
- Pre-rekey instead of post-rekey. Rekey the unit during the vacancy gap, not on the new tenant's move-in day. Avoids the awkward "tech in your unit while you're unpacking" situation.
- Maintain a documented bitting schedule. If you don't, the locksmith has to start from zero each time. Cost adds up.
- Negotiate a per-unit annual rate. For 20+ units we offer a fixed per-unit annual rate that includes one rekey per turnover plus emergency lockout response.

Frequently asked
Should Milwaukee landlords rekey between every tenant?
Yes. Most multifamily attorneys consider it standard practice and the cost is small relative to the legal exposure of a tenant returning with a copied key. Per-unit Milwaukee cost: $80-$150 for a 2-cylinder unit, $150-$250 for a 4-cylinder townhome.
What does it cost at scale?
Bulk pricing breaks the per-unit cost down. A 24-unit building rekeyed during a turnover wave: $1,800-$2,800 total, vs. $4,000-$5,500 if scheduled one-at-a-time. We schedule turnover rekeys against the lease-end calendar so multiple units cluster in one visit.
Can you set up a master-key system for me?
Yes, design a master + sub-master + tenant-key schedule, re-pin every cylinder, document the bitting. Cost: $400-$3,000+ for a building rebuild depending on size. After that, individual unit rekeys reference the existing schedule and cost $40-$80 per cylinder.
What's the legal exposure of NOT rekeying?
Wisconsin landlord-tenant law (Wis. Stat. § 704) doesn't explicitly require rekeying between tenants, but case law has held landlords liable when an old tenant returned with a copied key and committed theft. Insurance also usually requires reasonable security between tenants. The $80-$150 per unit is small relative to a single liability exposure event.
What about smart locks for rentals?
Increasingly common. Smart locks (Schlage Encode, Yale Assure) let you change codes between tenants instantly without a service call. Initial install: $200-$500 per unit + hardware. Long-term per-turnover cost drops to ~$0 (just generate a new code). Math works for high-turnover units (annual lease cycles).
Can you handle a 50-unit building?
Yes. We schedule large-property rekeys across multiple visits, working zone-by-zone to minimize disruption. Documented bitting schedule, numbered keys, optional master-key hierarchy. Quote per-site after a walk-through.
