Device lock software
the customer agreed to at the sale
Lock a financed phone from your shop. Unlock it in seconds when the money lands — even when the phone has no data. LetzPay Locker sets up at the sale with one QR code and keeps the conversation honest.
Control that fits behind a counter
Remote lock & unlock
One button in the retailer app or the dashboard. The lock screen names the shop and the amount due, so the customer knows exactly who to call.
Offline unlock codes
No internet on the phone and none at the counter? Generate an unlock code and finish it over a call.
Wipe & reboot reports
A factory reset or a reboot on a financed phone lands on the timeline while you can still act.
Factory reset protection
The setup arms a Google account prompt on reset, so a wiped phone comes back to you first — not to a new buyer.
SIM change alerts
A new SIM in a financed phone is the loudest warning there is. You hear about it with the new number attached.
App lock
While an instalment is overdue the phone can be held to its essentials — calls to the shop still get through.
What we will not claim
- ✓No magic. Anyone promising that no phone can ever be bypassed is selling a story. What we do is documented, reversible, and honest about its limits.
- ✓Agreed at the sale. Our shops put the lock in the agreement and show the customer how it works before they leave. That is the right way to use device control.

From handover to final instalment
Enrol at the sale
The customer's details and instalment plan go in first; the Setup QR enrols the phone as you hand it over.
Set the terms
Instalment amount, dates, grace days and who financed it. The lock follows those terms automatically.
Lock or unlock on demand
Automatic on a missed instalment, manual any time — and an unlock code in your pocket when the network is down.
Device lock software — quick answers
What does device lock software do?
It puts the shop in control of a phone sold on instalments: the phone enrols at the sale, locks when a payment is missed according to the terms you set, and unlocks the moment you record the payment.
Can the customer bypass the lock?
A determined person can always factory-reset a phone — nobody honest sells a lock that cannot be beaten. What we do is make it visible: a reset raises the wipe alert and the reboot report, and the armed Google account prompt means the phone asks for the shop's account before it sets up again.
Do I need internet to unlock?
No. The unlock can run from an offline code — read it over the call or send it by SMS.
Is it legal to lock a phone sold on EMI?
The device is the shop's security until the instalments are paid, and our shops put the lock in the signed agreement and demonstrate it at the sale. Use it on your own financed sales, transparently — that is how it is meant to work.
Does it affect battery or data?
No — check-ins are light and the customer does not notice the app day to day.
Lock and unlock a real test phone
Five test keys, fourteen days, the whole product. Nothing proves a lock like trying it yourself.
